The larger, heavier ring — for full key sets, tool tags, equipment tagging and anywhere a 25mm ring is working too hard. Highly corrosion resistant. 316L exhibits high resistance to corrosion and oxidation, and will withstand a multitude of washings with detergent, household chemicals and salt water. Rust resistant where it matters. Instrument tags, clinic carts, wash bays, tool cribs — 316L stands up to moisture, detergents and salt far better than ordinary 304 stainless. 2mm wire, not 1.6mm. A noticeably stiffer ring that resists splaying under a heavy key set. Opens with a thumbnail, closes flush. Evenly wound so keys slide on without fighting the coil and stay where you put them. Solid stainless throughout. No plating to chip or wear away.
