Silver Color Canopy for Closure Jewelry ø 1 mm

Cannottiglia silver color for the realization of jewelry like necklaces and bracelets with knots threaded on polyester thread. It is a metal filament wrapped in spiral on itself that resembles a small spring. Its function is to protect the ends of polyester thread that go into contact with the elements of the closure avoiding that the colana can break and thus guarantee a greater seal.
