Nice wee waterproof containers
I use these as waterproof containers for geocaching logs inside larger containers.

Cheap and cheerful
Bought for mixing paint for my airbrush, a task they are well suited for, but I doubt that any excess will keep for long as I doubt the seal is up to it. Good value if you want short term use or just a small graded mixing pot.

Die Behälter sind dicht und machen einen guten Eindruck, einen Stern ziehe ich hab da ich nur 99 Stück statt 100 hatte.

As described, didn't come across any "duds" and seem liquid tight (used for a fountain pen ink swap).
