This is Fast Cure glue used for tying flies and reinforcing fishing knots. Have you ever experienced 'line slipping' when tying mono to braid? Add less than a drop of this glue to the knot and let it dry for 15 seconds and you will never have a knot slip again!
This Zap-ca glue is the industry favorite for tying flies for beginner to experienced fly anglers.
Who doesn't love a super glue designed for fishing?!
