Single 120 Film holder.
For when you are overly cautious and want to throw your film in your bag. ;)
May not close completely when wrapped… (good indicator for unused). Shot film (no wrapping) fits loosely > I've taken a bit of 3mm depron and fitted this to the cap as seen on the cover photo. No more rattling.
Modeled to have a perfect friction fit on my MK4…
