COLLAR DE METAL PLANO CON CUADROS Y CIERRE CON LLAVE ALLEN

The Allen key lock gives it a solid, secure feel that snaps shut with no rattle. I wore it for a couple hours and the flat metal sat smooth against my collarbone without pinching. Honestly sturdier than I expected for the price.

The Allen key lock is the reason I picked this over other collars, and it hasn’t let me down—no accidental loosening during use. The metal edges are smooth enough that I forget I’m wearing it after a few minutes, though the flat design does take some getting used to. Solid buy for the price.

The squared shape sits surprisingly flat against the skin, and the Allen key lock clicks in with a satisfying, secure certainty. I've worn it for a few hours at a stretch and forget it's there, which is exactly what I wanted.
