WHAT IS MATTER
Matter is our popular science-themed subscription box. It's the only box to feature REAL scientific items rather than t-shirts, games, and books. Most months we have extra items, which we offer here to anyone who may be curious about what to expect in the subscription.
Please note: This listing is for a one-time box of an assortment of items and NOT a subscription. If you're interested in subscribing to Matter to get new, fresh items shipped to your door every month, you can find out more here.

Loved it!
For anyone that likes science, this is the most nifty box of cool things to get yourself or as a gift.
Exactly the right things! How did they know?
This is the BEST stem cell product! I specified that I love rocks and minerals, elements, interesting materials, NASA, and meteorites. I got them all! I also specified that I already had tiger's eye and didn't want anything radioactive, and they listened! This is the BEST deal on Stem Cell. If you want a bit of surprise or a great deal, this is the best product! You get five items and some informational cards. You also get a box to store all your Stem Cell stuff in! I will definitely be ordering again. This product gets 1,000,000,000,000 stars!
I love a good mystery box, and I was really pleased with what I received. Thank you!
I bought 2 boxes together vice the subscription and was thrilled to see there weren't duplicate items. Dad was happy with his new trinkets and fun facts.
WE TAKE SCIENCE SERIOUSLY
You deserve better than craft store science products. And we think learning is more impactful when you're holding a tangible piece of what you're learning about. That's why Stemcell exists.
We're dedicated to providing the best scientific products available—whether they're fragments of scientific importance, experimental activities, or just interesting things that scratch your curiosity itch.
With every new product launch, our list of new ideas gets longer rather than shorter. So check in often for our latest projects, and thanks for being a part of our endeavor to make the world a smarter place to live.
Believe in yourself; for everything else, there's science.
