If you’re a coffee drinker who also happens to be a fan of Lego or other building blocks, ThinkGeek has the perfect mug for you. It’s called the Build-On Brick Mug and is compatible with almost every major building block manufacturer out there. You can snap blocks onto the mug from Lego, Mega Blocks, PixelBlocks, KRE-O, and K’Nex Bricks.
The mug holds 12 ounces of your favorite liquid, including coffee. The outside of the cup has flat areas with holes to attach bricks that use pegs and the little raised circles we’re familiar with from years of building using Lego.
The cup is made from BPA-free plastic and is available now for $19.99. You have to hand wash the mud and I doubt you’ll be able to microwave it without melting it.
