Poxipol epoxy glue

Plastic two-component glue.
Just 10 minutes action.
Waterproof.
Strong bond

Personal feedback: I was searching for strong reliable glue to use it for the back side of my brooches, where I make an edging stitch separately from the piece itself. And when I found this one I am using it since. You get plastic pad and the stick with two tubes of glue that you can mix directly on this pad..Excess glue will dry and you can clean it later to reuse.  Yet you must be careful since glue isn’t transperent, sometimes it has slightly yellow tint, so you shouldn’t use it on some visible transparent surface.
