This leather card holder is a prototype (meaning it was used to experiment with techniques/size/shape etc). It is a thin but firm gray leather with hand-splattered green and lime paint on the front and back. It has a silver screw-back button stud closure and is unlined. It will fit all credit cards, folded bills, and perfectly fits your Covid-19 Vaccine Card.
Size: Approx. 4.5 x 3.25 inches (flat)
