I bought these sometime ago and never used them. I sold my TLR and have no need for them anymore. They would be great for someone wanting to shoot or try paper negatives. There is an attachment back and three holders. Not sure if everything you need is there, but it looks all there (no guarantees). The holders are in excellent shape and so is the back, looks unused. How about $50.00 shipped in the CONUS ONLY please. PM me directly if interested please. Paypal or USPS Money Order is fine. Thanks, Mike.
