THE NERDIEST BOOSTER PACK
Since 2018, every item in our monthly Matter boxes has shipped with a custom scientific info card—and collectors have been obsessed. Now, celebrating our 100th box milestone, we're releasing thousands of archived cards as standalone booster packs. Each pack contains 42 unique, tarot-sized science cards about real specimens, artifacts, and phenomena from our curated collection.
Every card details the item's scientific properties, historical significance, and why it matters. From fossils to space artifacts to lab phenomena, each one is a conversation starter disguised as a collectible.
Build your collection. Master the facts. Boost your brain. This is the ultimate release for science enthusiasts, niche collectors, and educators who demand authenticity with their wonder.
Get a free booster pack when you buy any 3 items from our Matter Items collection. Just add it to your cart along with the qualifying items and the discount will apply automatically. Cannot combine with some discounts.
Cards only. No specimens included.
