What's the difference between Mad Mattr and Kinetic Sand?

When we created Mad Mattr, we set out to make a better material — one that molds, cuts, and builds better than Kinetic Sand, and cleans up more easily. Mad Mattr is softer, smoother, and flows beautifully. Best of all, it never dries out, even when left out. We think we succeeded! 😄

What is Mad Mattr made of?

Mad Mattr's exact formula is a trade secret, but we can tell you it is 100% non-toxic, wheat-free, gluten-free, and casein-free. Mad Mattr is proudly made in Sweden using premium materials sourced from Europe — manufactured under strict European safety standards with absolutely no asbestos or harmful chemicals of any kind.

Is Mad Mattr asbestos-free?

Yes, 100%. Mad Mattr contains no asbestos whatsoever. It is non-toxic and manufactured in Sweden under some of the most rigorous safety regulations in the world. Safe for children ages 3+.

My child is allergic to gluten — is Mad Mattr safe?

Yes! Mad Mattr is wheat-free, gluten-free, and casein-free. It is completely non-toxic. If your child develops any irritation, discontinue use and consult a physician.

Does Mad Mattr contain soy, corn, latex, milk, or nuts?

Mad Mattr is wheat, gluten, and casein free. While we cannot confirm the facility is entirely nut-free, the formula does not contain soy, corn, latex, or milk.

Does Mad Mattr dry out?

Never! That's one of Mad Mattr's superpowers — it stays soft and pliable indefinitely, even when left out overnight.

My Mad Mattr feels crumbly — is it old?

Not at all! Mad Mattr flows best when warm. Work it in your hands for a minute or two and it will soften up beautifully, just like in our videos.

My dog ate one of your compounds (Mad Mattr, Kinetic Sand and Shape It!), do I need to take him/her to the vet?

If you are unsure how much your pet has consumed, or are concerned for your pet's safety, we suggest consulting with your vet. We do not test our products on animals.
