Relevant Play MAD MATTR Quantum Tool Box (Tool Box, 10oz Mad Mattr Included, 20 Tools Plus The Ultimate Brick Maker)

My 8 year old son and 3 year old daughter absolutely love this Tool Box full of Mad Matter and brick building tools. They will sit down and play with it for a good hour every time they get it out. The texture of the Mad Matter reminds me of kinetic sand, but it is much smoother and can retain its shape longer, especially if compacted well enough. This makes it much more fun and easy to build with. I have purchased this for gifts a few times because everyone who plays with it at our house loves it. I love that it all is in a tool box, which makes clean up and organizing easy!

Love the texture! Stays firm enough to bounce when packed and yet squishes like foam! We havn't experienced any of the colors coming off on our hands. Instructions say that sanitizers, lotions and super humid climates can cause transfer of color, but that it washed off easily with soap. The texture plates are super fun! Great sensory activity! I rated this a 4 because it seems like the hinges in the texture plates will break after repeated use. Hinges are already turning white and we've only used them a few times. Also, it's hard to avoid distorting or squishing the bricks once you start cutting into them using the miter box that has diagonal options such as to make a roof as pictured. The other miter box works great as you can see in the picture showing various sizes of bricks! The safe cutting saw is helpful. There is one tool with no instructions to it. Does anyone know what the purpose of this tool is?

We love this stuff! It's not quite play-doh but not quite kinetic sand. It's exactly what my son asked for!

I don't know why we waited so long to try this!! This is great stuff! We had so much fun creating legos ad building. My boys woke up this morning and it was the first thing they ask me..could they play with it! Perfect for our family of little ones 5 boys; 7-1...they all enjoyed it. We will certainly be purchasing more...it's my favorite of all the options available. By a long shot!

My three children, ages 2 years to 7 years, all love to play with Mad Mattr! While we have collected a few small brick makers and extruders through other kits, having more tools is always great. We've had nothing break, and they're easy to clean (just give them a firm rap on the table and any remaining Mattr falls out - it's not the digging & poking of Play-Doh).

received the mad matter tool box. the mad matter inside seamed old or defective. the product is supposed to be soft and pliable. these were very dry and hard to shape. other mad matter products were just as advertised . soft......

Kids love

Love the kinetic sand. It’s so easy to clean, fun to play with and honestly quite additive!!! I got a set for my office to play with. It’s relaxing! I recommend this brand over the other brands which I’ve also tried. Way to go Relevant!

Es fantástico para los niños. No mancha y dura con la misma textura muchísimo tiempo y es muy agradable al tacto. El maletín trae accesorios para hacer ladrillos y construcciones. Mi hija pasa horas jugando. Muy recomendable.

Unser Sohn ist hellauf beheistert! Bauen, kneten, zerschneiden, stapeln! Tolle Box, toller Spielfaktor.

My daughter loves the mad mattr sand very much. The texture is fantastic, she can play for a long time with it, just to feel the sand with her hands.

Meine Kinder haben viel Spass an diesem Knetsand. Er hält was er verspricht. Man kann ihn auch vom Boden gut wieder aufheben wenn mal was runterfällt. Haben ihn nochmal für meinen Neffen bestellt.

Very good value and kid loves it
