These cross-lock tweezers work by reverse action, opening when pressed and closing snugly when released. They are made from stainless steel, measure 4.125 inches, and are powder coated at the handles. The tips are highly pointed, making it a great tool for picking up beads. Many beaders, including Orly (the inventor of the OGees Board) enjoy working with the cross-lock tweezers when designing with larger beads, such as 8/0. They work well with 11/0 as well.
