Title: Niji Waterbrush - hate it!
Review: I bought one of each of these and am very sorry I did. Once I fill them and screw the cap back on - I CANNOT get it back off! No matter what I do! Even with pliers. And I do not have a lot of strength in my hands to screw things on tight so I think it must be the product I liked the brushes while I used them but if I can only use them once, what is the point? I would not buy this brand again.
