Review (5/5): Both work great!
Both tanks work great for helping keep my lash adhesive’s at correct humidity. The black tank is nice in that it has the locking feature so you’re sure it is completely sealed, & there’s plenty of room for at least 3 small bottles & a silica packet. The pink one is also nice, as it has a button you press as you push the lid down to ensure it is sealed properly. It has a foam separator that allows for 3 small glues & a silica packet as well. I like that they came in a pack of two, since I have two locations I work from.
