The listing, Camera Gear! Developing Tank & Reels! has ended.
You're bidding on a developing tank and 3 film reels: two (2) for 35mm film and one (1) for 120 film.
You can purchase the appropriate chemicals from a number of online stores, as well as bottles to hold the mixtures (the chemicals come in powder form).
It takes a bit of skill to get the film on the reel, so get an old or cheap roll of 35mm film and practice! You'll have to load the film in the dark, then place the reel in the tank, then close the tank. Only then can you turn on the lights!
S/H won't be much, as the tanks and reels don't weigh much.
