OptiMALE - FlexiSteel - Mjuk silikon med innerkärna av metall - 43 mm

The metal core inside gives it just the right amount of rigidity without that cold, unyielding feel of a pure steel ring. I sized down from my usual 45mm and the 43mm fits snug but still comfortable after a solid hour of wear. The open-sided sheath design keeps things secure while letting me adjust

Slipped it on warm and the silicone felt almost silky against the skin—the open-sided design means you get that solid steel weight without any pinching. Stayed put during use and came off just as easily when I needed it to.

The metal core inside the silicone gives it just the right heft without any of the cold hardness you'd expect. I've worn it for longer sessions and the 43mm fit stays comfortable while the open-sided design keeps things feeling secure.
