Why settle for the standard mug when your office cup could mean playtime too? This Build-On Brick Mug is functional, totally customizable, and just plain fun.

This mug is designed with a peg and hole surface that you can add toy construction bricks to (because who doesn't love Legos?!). So not only will your office cup hold your caffeinated beverage of choice, it can be as playful or as practical as you want it to be.

Also, it'll be really hard for Susan from Accounting to take it again. Get the Build-On Brick Mug for $19.99 from the Someecards store - that's 50% off the original price of $39.99.
