Review on Chums Fish Rope Eyewear Retainer by Runbi Alvarez

I originally had croakies on my ONO sunglasses but I never liked them because they were quite thick and stiff. Always rests on my collar or sticking out to hit the headrest. I saw them and read the reviews. I was trying to understand what 3mm really is, apart from converting to inches. That's about the thickness of nickel. Anyway, these mounts are tight, but that's what you want, and a little saliva helps. They lie flat and are exactly what I was looking for. I highly recommend!
