Other mugs just have one purpose only and that is to serve you your drink. But this Creative Build-on Brick Mug has built-in slots for kid's building blocks. You can have separate building blocks and try building a design onto your mug. Kids will definitely love it! It is not only a mug but also a cool building blocks toy!
