We are happy to return film spools and cassettes that are identical in their function. For instance…if you send us a 127 spool we will send you a 127 spool back. We will try to get your original film spools and/or cassettes back to you but this is not guaranteed. We have found it exceedingly difficult to have a working system of keeping track of peoples film packaging while dealing with hundreds of rolls of film in the dark. A very effective system is in place for keeping track of who’s film belongs to who but within the system there is no practical way to also include the film packaging. Most often we will get you your precise packaging back but this is not guaranteed. The film spools, cassettes and boxes are of little or no monitory value.
