Made of thin Super Mica, the primary use of these shims is to shove open a door latch.
Place the card in-between the door and the frame, find the door latch, apply the right amount of pressure and technique and you’re in.
Two cards in each order (coin not included)
Tip: Not just a shim, you can draw and write on these cards with a marker pen which could make them a backup map or way of passing information.
