## Description

desertcart.com: Relevant Play Mad Mattr Quantum Tool Box - 20 Construction Tools with Brick Maker, Never-Dry Sensory Dough for Kids Ages 5 and Up, Moldable Compound, No Mess, 10 oz : Toys & Games

## Features

- NEVER-DRY SENSORY DOUGH THAT OUTLASTS EVERY KINETIC SAND OR PLAY FOAM KIT - Kinetic sand scatters. Play foam breaks apart. Cloud dough dries out. Mad Mattr compound is engineered to stay soft, moldable, and workable indefinitely so kids ages 5 and up can build, break down, and rebuild the same pack for months without replacing a single ounce.
- THE MOST TOOL-COMPLETE DOUGH CONSTRUCTION KIT AVAILABLE - 20 purpose-built tools in one portable case: 3-piece Ultimate Brick Maker, curved brick maker set, texture plates, molds, living hinges, miter boxes, safe cutting saw, and cutting tool. Press uniform bricks, stack real structures and construction play that goes well beyond any standard play dough tool set.
- STICKS TO ITSELF, NOT TO YOUR HOME - Unlike kinetic sand that scatters across carpet, or slime that sticks to everything, Mad Mattr compound bonds only to itself and releases cleanly from hands, tables, and surfaces. No mess play dough that actually lives up to the claim, ideal for home, classroom, or sensory bin play.
- NON-TOXIC, GLUTEN AND WHEAT-FREE, CHILDREN'S PRODUCT CERTIFIED - Non-toxic, gluten-free, wheat-free, and casein-free formula backed by a Children's Product Certificate. Not for children under 3 due to small parts. Adult supervision recommended for younger children.
- COMPLETE KIT IN A PORTABLE TOOLBOX - 10 oz of Mad Mattr in two 5 oz mystery-color packs, 20 construction tools, and a durable storage toolbox, 12 x 7 x 6 in, 2.5 lbs. No replacements needed. Open it, play, store it. Made in Sweden.
