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 and paleontologists in the field.

Start your personal museum of natural history.

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

Historic Artifacts

Artifacts are like human-made fossils—objects that were created by people doing incredible scientific things. Our artifacts go through a tedious process of provenance verification and expert authentication.

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

[ ITEM #328 - CONCORDE SUPERSONIC AIRCRAFT AIRFRAME FRAGMENT ]

Exotic Rocks & Minerals

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

Learn about the science-based properties and applications of natural rocks, crystals, and minerals.

[ 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.

...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.

FAQ

Will I receive repeat items?

Most subscribers will never get a repeat item. Each Matter box is unique, packed with scientific stuff you haven't seen before.

Occasionally we revisit a particularly amazing item, but we'll only repeat an item if it's been at least 3 years.

Do you offer educational discounts?

Yes, we do! We're all about spreading the love for science, and we understand that schools and teachers (and students) have tight budgets. That's why we offer special educational discounts to help bring our Matter boxes into your classrooms or learning programs.

These boxes are perfect for sparking students' curiosity and complementing your science curriculum.

How can my company collab with Matter?

If your lab or company produces a scientific item, or if our organizations' missions align, we would love to explore collaboration. Whether you're a burgeoning start-up or an established industry leader, we're open to a range of partnerships that drive science forward.

Past collaborations have included sponsorships, sourcing custom items, and even curating themed boxes.

Can I get Matter boxes for my work team?

Absolutely! Matter boxes are a fantastic way to spark curiosity and add a bit of science fun to your workplace. Whether it's for a team-building activity, a unique reward, or just to give your office a cool science vibe, we've got you covered.

We'll make sure they're packed with intriguing items that'll get everyone talking. Plus, it's a great way to mix up the usual office routine with some brain-tingling science.

How many items will be in my box?

To ensure we get a varied mix of types of items, we guarantee a total value of $60+ in each box rather than a specific quantity of items. Historically, we've stayed between 2–8 items in every box, but each of these boxes had a similar total value.

The Coolest Subscription Box!

I have been more than happy with every single Matter Box I have received. I have incorporated most of the items into my museum styled living room and the display is complimented frequently by guests. The boxes come with cards that explain what the items are. I have put the cards in a binder and find myself reading through them often and appreciating being able to have these little bits of science and history in my life.

Keeps your mind young

A wonderful distraction that flexes the sense of wonder you lost over the years, yet still educates you with something you can hold in your hand.

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.
