So. I only have 2 tanks. I have more juices than that so I have to rotate cartos every now and then. Sometimes I want to go back to that flavor but I dont want a whole tank of it. To vape the punched cartos with no worry of leaking I cut the closed end off a condom and use the sleeve to cover the holes while the cartos are not in a tank. Just thought I would share.
