So far there have been no problems with the c-41 chemicals I have used. I have to use some glass beads to remove the little air space at the top so the chemicals don't go bad prematurely. seals airtight. They have a tamper evident ring (I guess that's what it's called) like milk jugs that break as soon as you put the lid on for the first time and you know it was open. It didn't bother me, but it seems like it could be a nice feature for something like this.
