Mini-Hobby-Klammern x6

Gets the job done.

These are quite strong and useful for holding parts together while the glue dries. My only issue with them is that the black rubber pads on the end of the clamps slip off or misalign and always need adjusting. Even when the clamps haven't been used for a few minutes they will stick to each other and upon opening one will come off which is quite annoying especially as a product intended for convenience. The product would be perfect if not for this, should be easy to fix by GSW.
