Satisfyer Duelist - ダークブルー

Wasn't sure an adjustable ring would actually stay put, but the fit dials in snug and doesn't slip mid-use. The flexibility makes it way more comfortable than the fixed-size one I had before. Genuinely surprised how much difference that makes.

Exactly what I needed — the adjustable fit means it actually stays put instead of sliding around mid-use, which was my problem with fixed-size rings. The dark blue looks sharp too, and cleanup afterward was quick.

The adjustable fit is what sold me—I can loosen or tighten it depending on the day, which most rings I've tried don't allow. Stays comfortable through longer sessions without pinching.
