The not-so-famous LIMITED-USE keycards from the game Escape from Tarkov.
This card represents both the 21WS and #11SR, the only difference is the handwritten text on the back of the card, add whichever you like more, or leave it plain, it's your card!
For this print, you need to have AMS or other multi-color system.
I would recommend a layer height of 0.08 mm or less.
The card size is 85.6 x 54 x 0.8 mm.
