Customer ReviewsWrite a review
This kit is a ton of fun, even for me as an adult. The little bricks fit really well together and since Mad Mattr holds its shape pretty well it's a really fun compound to build with. It's kind of like making your own Legos to build with. Definitely recommend this set if you've got a little architect at home or if you happen to want to mess around with building things yourself. The one thing I wish was different is the pack of Mad Mattr that comes with it. It doesn't come in the resealable bag so you have to find a container to keep it in yourself.
I think it'd be really interesting if Relevant Play came out with another brick maker set with different sized brick makers. The same width but maybe different lengths, like half as long. I was making a little 4 wall brick building alternating the placement of the bricks like you would see in a real wall, and I definitely came across the need for bricks half as long when I was trying to leave gaps in the walls for doors or windows.
