Is it a dough? Or is it sand? Mad Mattr is a compound of its own! This super mold-able, yet soft material lets you build with it when compacted, but turns incredibly soft and falls apart when stretched! Almost like moon sand, but much less messy and much more fun! Whether you're looking for something to keep your hands busy or to craft with, Mad Mattr is the choice for you! This box of Mad Mattr contains a mold to create your own building bricks! An awesome way for kids to express themselves, all the while have fun. A great gift for anyone 3+. Show more
