Lumsburry Build-on Brick Mug Review: A Fun Desk Toy First, a Mug Second

Lumsburry's build-on brick mug is a 12-ounce plastic mug whose sides are covered in studs, so you can snap building bricks onto it and decorate it however you like. It comes with a small, random assortment of bricks and a minifigure to get started. As a gift for anyone who loves building sets it is a near-certain hit. As an everyday mug, it asks for a few compromises.

TL;DRThe Short Answer: Is the Lumsburry Build-on Brick Mug Worth It?

Half the fun is building on the mug, and its studded sides take standard bricks from an existing collection, which matters because the included pieces are a small, random assortment. It is a plastic mug, so no microwave or dishwasher, and it runs bulkier than a regular cup. As a gift for brick fans, it rarely misses.

What Stands Out

  1. Studded sides let you build bricks onto the mug and change the design whenever you like.
  2. Comes with three packs of bricks: two random toy sets and one random minifigure.
  3. Holds 12 ounces, about 350 ml, of coffee, tea, juice or a fizzy drink.
  4. Made from BPA-free, food-grade plastic that can take hot drinks up to 100°C.
  5. Hand wash only, and not for the microwave, oven or dishwasher.
  6. Contains small parts: recommended for ages 3 and up with adult supervision.

Strengths and Drawbacks

What works

  • Build and rebuild designs on the studded sides as often as you like.
  • Takes standard bricks from an existing collection.
  • A reliable gift for building-set fans of all ages.
  • Holds 12 ounces and takes hot drinks up to 100°C.
  • Plastic body feels sturdy and survives knocks better than ceramic.

What does not

  • Hand wash only, and no microwave or oven.
  • The included bricks are a small, random assortment.
  • Studs and bricks make it bulkier to hold than a plain mug.
  • Small parts are a choking hazard around young children.
  • Bricks built near the rim can get in the way of drinking.

Features in Depth

01

Build-On Studded Sides

Build Surface Studded sides Compatibility Standard building bricks Colour Black

The whole point of this mug is the studded outer wall, which works like a curved baseplate for building bricks. You can snap on a pattern, a scene or a nameplate, then pull it apart and start again, so the mug never has to look the same twice. Fun is one of the most praised qualities, and it is the reason the mug has been a hit at white elephant exchanges and as a family prize. The studs take ordinary bricks from other sets, which one owner confirmed with their own collection, and that matters because the builds you can make depend on what you have to hand. The design suits a desk or office, where a small scene on a mug is a conversation piece, and it lets you personalise a gift in a way a printed mug cannot. Keep builds away from the rim so they do not get in the way when you drink.

The Included Brick Packs

Brick Packs 3 Contents 2 toy sets and 1 minifigure Selection Random

Each mug comes with three packs of building bricks: two random toy sets and one random minifigure. Lumsburry is clear that the shapes and colours are random and vary by production batch, so two mugs bought together may come with quite different pieces, and you cannot pick a theme. Owners have found the bricks colourful and fun to start with, but the included pieces are a small assortment rather than a full set, and the real fun comes when the recipient adds bricks of their own. If you are buying for someone without a collection, adding a small bag of assorted bricks turns it into a much more complete present. For children, the loose bricks and minifigure are also the parts to watch, as they are small enough to be a choking hazard.

Capacity, Material and Heat

Capacity 12 oz (350 ml) Heat Limit Up to 100°C Material BPA-free plastic

The mug holds 12 ounces, about 350 ml, which is a normal mug size, and it is made of BPA-free, food-grade plastic. Lumsburry says it can take hot water or coffee up to 100°C, so freshly boiled tea and coffee are fine, and it is also suitable for juice and carbonated drinks. Being plastic, it is lighter than a ceramic mug and less likely to break if knocked, which suits a desk, and one owner found it solidly built. The plastic does rule out the microwave and oven, so reheat drinks in another cup. The studs and any bricks add bulk around the outside, which is why size divides opinion: one owner found it bigger than a regular coffee cup, and others think it is too big to hold comfortably. It measures 5.5 inches wide and 4.9 inches tall.

Cleaning, Safety and Gifting

Care Hand wash only Age Grading 3 and up Packaging Gift-ready carton

The mug is hand wash only and should not go in the dishwasher. Take the bricks off first, wash the mug and the pieces in warm soapy water, and let everything dry before rebuilding, since water trapped between bricks and studs is slow to evaporate. A soft brush helps clean around the studs. On safety, Lumsburry lists a choking hazard because of the small bricks, grades it for ages 3 and up, and says children using the mug must be accompanied by adults. As a gift, it is one of the easiest picks for anyone who loves building sets: it has worked as a white elephant gift, a teacher's present, a birthday gift for a brother and a present for a husband who loves building bricks. It ships in a carton designed to protect it in transit, which also makes it easy to wrap. Value is mixed, mainly because the included brick assortment is modest.

How We Scored It

Based on
The manufacturer's published specifications and the product's live Amazon listing.
Owner rating
4.7 out of 5 on Amazon, recorded September 27, 2026
How we score
We score each thing that comes up most in owner feedback on the Lumsburry Build-on Brick Coffee Mug. Eight things come up most in owner feedback: five draw praise, two split opinion and one draws mostly complaints. Its ratings average 4.7 stars (81% five stars, 12% four, 5% three and 2% one or two), so every score starts at 94, that average on a 100 point scale. Where opinion is split, we take off 6. Where it draws mostly complaints, we take off 12. Then we read eight owner reviews in full (every one we found gave it four or five stars) and move the score up to 5 points either way depending on how the owners who mention it rated the product. Our overall score starts from the same 4.7 star average and loses 0.1 for each thing that draws mostly complaints, with 0.1 more when at least a tenth of ratings are one star, never more than 0.3 in all. Here that takes off 0.1, which gives 4.6. Read our editorial standards

What Buyers Say

It is a favourite gift, especially for brick-building fans, and the concept goes down well: it works with regular bricks from an existing collection, feels sturdy, and one owner enjoys building little scenes on it while drinking coffee. Size divides opinion, with some finding it perfect and others too big, and value is mixed.

Setting It Up

  1. Wash before first use

    Hand wash the mug in warm soapy water and let it dry.

  2. Open the brick packs

    Unpack the two toy sets and the minifigure, keeping small pieces away from young children.

  3. Build on the sides

    Snap the included bricks, or bricks from your own collection, onto the studded sides.

  4. Keep the rim clear

    Leave space below the rim so builds do not get in the way when you drink.

  5. Fill with a drink up to 100°C

    Pour in coffee, tea, juice or a fizzy drink. Heat drinks in another cup, as the mug cannot go in the microwave.

The Verdict

4.6Out of 5

Lumsburry's build-on brick mug is a toy you can drink from, and that is exactly why it works as a gift. The studded sides take standard bricks, so a building fan can decorate it with pieces from their own collection and change the design whenever they like, and it has been a hit at white elephant exchanges and family game nights. As a mug it is decent: 12 ounces, BPA-free plastic that takes hot drinks up to 100°C, and sturdy enough for a desk. The compromises are real, though. It is hand wash only, cannot go in the microwave, feels bulkier than a plain mug, and the included bricks are a small, random assortment. Small parts also mean it needs adult supervision around young children. Buy it for the fun rather than as your only mug, and it is a delightful present.

Who should buy it

  • Building-set fans
  • White elephant and office gift shoppers.
  • Parents buying a fun mug for a supervised older child.
  • Anyone who wants a desk mug that doubles as a display.

Who should skip it

  • Anyone who relies on the microwave or dishwasher.
  • Households with toddlers who could reach loose bricks.
  • People who prefer a slim, plain mug in the hand.

A fun, well-made gift for anyone who loves building bricks, as long as they do not mind hand washing a slightly bulky plastic mug.
