What a good idea. I wonder what other containers will fill this need?
eBay: Plastic Film Cans for 120/220 roll film (item 7605790972 end time Apr-07-06 09:37:21 PDT):
If you do much field shooting with 120/220 film, you know how handy it would be if medium format film came in waterproof plastic cans like 35mm film does, so you wouldn’t have to worry about the paper tab cominug unglued and unwinding in your bag, or rain falling on your film and warping the backing paper, etc.
As it happens, old-style 13-dram pillbottles from before the Tylenol poisoning scare are a perfect fit. They’re dark amber, watertight, snow-proof, and hold 120/220 format rolls perfectly. They’re a close enough fit that film still in its wrapper won’t rattle around, but exposed, unwrapped film will, so you can tell fresh and exposed film apart without even opening the bottle.
Looks like these are pretty common in the pharma trade, as cheap as 9¢ apiece.
