Small ring closing pliers that are 5 inches and made of 410 ASTM stainless steel. These pliers work best on rings 1/2 inch or smaller in diameter and up to 8 gauge in thickness. The head of the pliers has deep grooves for closing rings. The brass tips eliminate the risk of scratching your jewelry. Brass is softer than steel so misuse can cause the tips to bend and deform; use carefully!
