Review on 👓 Premium ECO Leather Eyeglass Chains for Women and Men - Glasses Strap Holder - Eyeglasses Chain Cords String - Stylish Eyeglass Lanyards - Convenient Neck-Hanging Eyewear Holders by Kyle Collins

I really like how light weight the holders are. I'm not sure what Eco leather is but I like it. I had to clean them today and they were easy to clean and dried quickly. Anyway, they were a little difficult to get onto my glasses, but they haven't slipped off either! I cycle a lot and my other holders would get caught in my hair, cling to my neck, etc. I don't even know I have these on when cycling. I guess my only "complaint" is that when I try to shorten the length, it doesn't stay put. Hardly anything to really complain about though. Really happy with them.
