21 Subscription Boxes That People Actually Swear By
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.
