I have been getting requests for something similar to this for awhile now. Here is my shot at it. It's a simple bi-fold body with a plastic translucent window to display a dope data card, range card or any other 3"x5" card.
The wallet can be secured to the arm with the two included 1" webbing straps or attached to a pack or vest by the PALS webbing on the back.
I have not determined pricing yet since this is just the initial design, but I should have that lined out soon.
