7ML Standard Silicone Concentrate Containers. Finally a solution for the problem of sticky concentrates. The Cannaline non-stick container is generously sized and the ONLY clear unit available. We manufacturer them with food grade silicone and even the gooeyist material will NOT STICK to it. They allow patients to use the total contents of the container down to the last dab. The seal is a an airtight, pop-top/screw-top combo that will not come off accidently, even if dropped or bounced off the floor.
