Firefly - Suave 睪丸拉伸器 - 藍色 - 夜光藍色睪丸環

Didn't expect the glow to actually be this bright, but it's a fun touch in low light. The fit stays comfortable for hours thanks to how stretchy the silicone is.

The liquid silicone is ridiculously soft, no pinching or chafing even after a couple hours. I was worried a stretcher would feel like a chore, but the fit is comfortable enough that I forget it's on.

Didn't expect the glow to be this fun honestly, my partner got a kick out of it in the dark. Fit is snug without pinching and it stayed comfortable the whole time, which is rare for me.
