Up for sale a dark-brown cardholder made by Corter. I've never used it, and don't intend to because it doesn't suit me. It measures 3.25" by 4.5" $45 shipped. (reign not included).
Re-used his photos because it can't get the details as clear on my crappy camera.
His comments :
BxC cardholder! it's dark brown. The white on the inside and uneven tones are due to a special wax treatment, because the leather is hand dyed. it will mellow out with use.
