The broad flat jaws have a form fitting smooth non-marring plastic nylon cover to protect your jewelry from scratching. These imported 5-1/2" long parallel pliers have spring loaded handles so they always start in the open position. Maximum jaw opening is a little over 3/8" (10.5mm). The jaws are 5/16" (8mm) wide. Made in Pakistan.
Great quality except for the plastic jaws. Using them to install 2.8 mm jump rings and smaller. Would like the the plastic to fit more exact and flat. Did modify them and worked ok. Would be no problem on bigger jump rings. 💪🏻
