What will you build? Review: Better than kinetic sand! All the kids love it! - 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! Review: Why did we wait so long!? - 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! ## Features - The perfect solution for hassle-free, mess-free creative play, the Mad Mattr Toolbox is an all-in-one creative extravaganza! - Build amazing Mad Mattr creations with 20 included tools! 10oz Mad Mattr in 2-Mystery colors including the Brick Maker!

All the kids love it! *by A***R on November 15, 2019* 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! ### ⭐⭐⭐⭐⭐ Why did we wait so long!? *by A***Y on March 18, 2020* 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! ### ⭐⭐⭐⭐ Great sensory activity! *by A***R on January 30, 2021* 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? ## Frequently Bought Together - Relevant Play MAD MATTR Quantum Tool Box (Tool Box, 10oz Mad Mattr Included, 20 Tools Plus The Ultimate Brick Maker) - Mad Mattr Super-Soft Modelling Dough Compound That Never Dries Out by Relevant Play (Green, 10oz) - Mad Mattr Ultimate Pack, Fun for Ages 3 and up, 10oz of Mad Mattr, Extruders, Ultimate Brick Makers, a Safe Cutting Tool, Non-Toxic Dough and Never Dries Out --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/88439992-mad-mattr-quantum-tool-box-tool-box-10oz-mad-mattr](https://www.desertcart.sg/products/88439992-mad-mattr-quantum-tool-box-tool-box-10oz-mad-mattr) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-04-26*
