This sale is for a Mamiya 645 120 insert (complete with the storage box). This insert is in near mint condition with only minimal signs of use.
This insert allows you to pre-load additional films for quick reloading of your Mamiya 645 camera or back. It is suitable for use with the Mamiya M645, M645J, 1000S, 645E, Super, Pro and Pro TL cameras.
If you already have an extra insert, get yourself another one – you know how useful they are; if you have not you just will not believe how much more convenient film loading has suddenly become.
