Why the Keychain Vault^™ ?
I could not find the right keychain case for the micro SD cards I use for file backups and disk images. I wanted it for a keychain, and indestructable, water resistant, dust proof, as well as an open standard to hold future micro cards and sim.

Why is it square inside?
I wanted the split ring attachment inset, and the design provides an extreme crush resistance. The inside dimensions will handle future generations of microcard.

Incredible Disaster Recovery
The small storage format micro cards have been evolving quickly and now 1TB cards are available. The 512GB, 128GB, and 64GB micro SD cards are now readily available with prices dropping weekly. Choose carefully, as there are lots of fake cards.

Holding six micro SD cards with some padding, it's a unique gadget. Hand them to your leadership team, your video team, or your drone crew.
