I purchased these a few years ago, but never used them because I found a method of tray developing that works for me. Anyway, it is time for them to move on to a new home. These tubes will accept up to 8x10 (exterior dimension: 10.5" for the tube and 14.75" for tube and cap). How about $75 + shipping. I'll cover the paypal fees. PM me if interested. Open to offers!
