WHAT TO EXPECT

Every month's box has all-new items, but here's some of the common types of items to expect. Think of these like personal museum exhibits.

Museum-Grade Fossils

Fossils are the rocky remains of previous lifeforms that called this planet home millions to billions of years before we came along.

We source our fossils from the most trusted experts in the field, often digging up the creatures themselves.

Preserve these precious remains like your personal museum of natural history.

[ ITEM #295 - SEA SNAKE FOSSIL - AGE: 55 MILLION YEARS ]

Historical Artifacts

Artifacts are like synthetic fossils—objects that were created by humans doing important scientific things.

By preserving these relics, you're creating a record of our species' advancement.

Our artifacts go through a tedious process of provenance verification and expert authentication.

[ ITEM #235 - NASA EXPLORER 7 SATELLITE TELEMETRY DATA TAPE ]

Exotic Rocks & Minerals

Our species made it's first big leap—into the Stone Age—when we discovered we coud make useful stuff with rocks. And we've been hooked on them since.

Learn about the physical properties and scientific applications of natural rocks, crystals, and minerals.

Note: We love a good crystal, but you won't find any metaphysical properties here.

[ ITEM #040 - NATURAL CUBIC PYRITE CRYSTAL ]

Meteorites

These fragments of other worlds ended up colliding with our speck of a planet after drifting through the immense void of the universe.

Meteorites are among the most precious items we feature, which is why we have each of our meteorites fully analyzed, authenticated, and classified.

[ ITEM #248 - MARTIAN METEORITE NWA13187 ]

...And Much More

Other items have included research equipment, experiments, clever trinkets, and interesting gizmos.

We've even partnered with some of the biggest online names in science, like @physicsfun and Tyler Thrasher to develop new and innovative scientific items not available anywhere else.

[ ITEM #281 - GLASS KLEIN BOTTLE ]

We only include verified authentic items in Matter. We work with reputable collectors, and regularly consult with our network of scientists and experts.

If we aren't 100% confident, it doesn't make it in the box.

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.
