Snag wizard

Quickly repair minor damage
Thickness: 0.8 mm
Made of hardened steel and coated brass
The snag wizard is a 0.8 mm-thin repair nail that can be used to effortlessly remove protruding threads. This special nail has a spiral-like, ribbed end instead of an eye. It is simply inserted directly next to the damaged thread through the fabric or knitted item. By turning it several times, the thread can be snatched and pulled on the rear. This allows for minor clothing damage to be repaired very easily.
