Secure-Lock Micro SD Keychain Case

Never lose your memory cards again.

This is not just a storage box; it is a secure vault for your data. Designed specifically to hold 2 Micro SD cards, this case solves the common problem of 3D printed screw-cases coming loose in your pocket.

🔒 The "Key-Lock" Mechanism The genius of this design is that it uses your keyring to lock the case shut.

Screw it shut: The cap uses a strong threaded connection.
Insert Keyring: When fully closed, the hole in the cap aligns with the hole in the body.
LOCKED: Once you slide your metal keyring through, the cap cannot rotate.
Secure: To access your cards, you must intentionally take it off your keyring. It is physically impossible for this case to unscrew while attached to your car keys or backpack.

✨ Features

Perfect Fit: Snug slots for 2x Micro SD cards (easy to insert and remove).
Debris Protection: The threaded seal keeps pocket lint, dust, and moisture away from the contact pins.
EDC Friendly: Small, rounded, and lightweight.
