Perfect She Loved It!

All the included items were outstanding! It is so nice to watch someone open a gift and spend time examining and reading about each specimen.

Best of Matter - Very interesting content!

I ordered a Best of Matter Box as a present and me and the person was very satisfied with the contents. Really interesting small articles. I ordered to Germany and delivery took a bit longer (around 6 weeks). I contacted the store just in case the package was lost and they replied quickly and were very nice. Overall, would definitely order again.

Love this!

This is the most fun box I’ve ever had! I really love having the scientific artifacts and they are really getting my nieces and nephews excited about science❤️🌱🐛 I also really appreciate that they plant a tree for every order.

S.J.B. (Minnesota, United States)

This was my first purchase and I signed up for the monthly box immediately after receiving this “best of” collection. I find the items to be fascinating, but I also can’t wait to share them with my kids and students!

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.
