WHAT TO EXPECT
Every month's Matter box is a unique experience, but here's some of the common types of items to expect. Think of these like personal museum exhibits.

[ ITEM #332 - FRAGMENT OF THE EARLY SOLAR SYSTEM ]
Meteorites from Outer Space
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, IMCA-authenticated, and classified by The Meteoritical Society.

[ ITEM #021 - TRILOBITE FOSSIL - AGE: 500 MILLION YEARS ]
Museum-Grade Fossils
Fossils are the rocky remains of previous lifeforms that called Earth 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 #328 - CONCORDE SUPERSONIC AIRCRAFT AIRFRAME FRAGMENT ]
Historic Artifacts
Artifacts are human-made relics—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 fragments, you're creating a record of our species' achievements.

[ ITEM #134 - ZIRCONIUM NUCLEAR REACTOR CLADDING ]
Fascinating Materials
Sourced straight from laboratories and industrial niches, some of our most surprising items are human-made materials with unique physical properties.

[ ITEM #046 - PURE BISMUTH CRYSTAL ]
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.

Expert-Written Research Cards
Each item comes with a collectible science card to give you insights, context, and history of every piece of Matter—as well as a starting point for your own in-depth research.
These collectible cards also include each item's official Matter catalog number.

FAQ
What comes in a box?
Every month of Matter is unique, but a typical box includes 2-6 items covering a range of scientific areas. Every item also includes a research card.
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.
How many items will be in my box?
Most months contain 5 unique items, and have historically ranged from 2–8 items.
Some items are simply more valuable than others, so rather than promising a specific number of items, we curate each box with a total value of $50-$75 so that you get your money's worth every time.
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.
Apply for educational discounts here, or send us a purchase order from your school. Let's make science exciting and accessible for your learners!
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.
Just let us know how many you need, and we'll handle the rest!
Where do you ship?
We currently ship globally via USPS or UPS
When will I receive my order?
Due to the complex prep and assembly process for each unique item, each month's batch ships together, typically around mid-month.
See the banner above to find out if this month's batch has shipped. If it has already shipped and you'd like your first box asap, consider adding a discounted past box to ship immediately while you wait for our next batch.
You'll receive a tracking number via email as soon as each box ships.
Do you have a teacher or educator discount?
Absolutely! Honoring our educators is so important to us.
Our educational discount is 15% off every order. Get your unique discount code at here.
What is your return or exchange policy?
If Matter isn't quite what you expected, or just doesn't work out, connect with our team so we can make it right.

AUTHENTICITY GUARANTEED
We adhere to the highest standards of authenticity when it comes to our rare and collectible items.
We source our items from the most reputable collectors and suppliers. Then we utilize our network of scientists and experts to assist in the rigorous process of validating each item's provenance.
If we aren't 100% confident an item is authentic, it doesn't make it into the box.
Our meticulously curated collections are designed to inspire, educate, and resonate, all while maintaining an unbreakable commitment to authenticity.
WHERE OUR ITEMS COME FROM
Since 2015, we've been cultivating a supplier network that bridges every corner of the scientific world.
From fossil excavation sites to state-of-the-art laboratories, whether we're looking for a rare mineral specimen or a cutting-edge piece of technology, our network allows us to source virtually anything in the realm of science, while ensuring quality and authenticity.
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.
