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 ]

So much fun

We love this box. We got it for our son for Christmas a few years ago and he asks every year to renew it. His friends & his grandma look forward to the box each month. He first got this in middle school. He is a sophomore now and just asked I'd we are renewing the box again. So much stuff to play with and research and just hold.

Best Display Pieces

I have gotten several of these now, and in moving I wrapped nothing more carefully than what I got in the boxes.
The things are genuinely so fascinating, so cool, and I LOVE the cards that come with them. We’ve had people cat sit and did a scavenger hunt of the artifacts I had, and I have shared them and their stories with so many people. They are such interesting and wonderful conversation pieces and so much fun to learn about.
They also do an excellent job of reminding me of the wonder of God’s great creations- all the wonders and joys of the world and humanity, in one little unassuming box.
