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 Brad Collins

To be honest, the only difference I’ve noticed is the fastener is connected to the rubber knot, not to a clip. It’s been my experience that the rubber stretches out on the loop within 10 to 14 days before it needs re-tightening which has been the case on all of the eyeglass holders I’ve purchased in the past. I just tightened the loop today. After the 2nd tightening stretches out, you need to change straps. The best thing about your product is the additional loops. I wear prescription eye glasses and sunglasses and when I’m out and about (outdoors to indoors), my holders get tangled. It would be a nice feature to have an extra length choice for those of us who wear both eye and sunglasses.I like the leather straps. I also think it would be nice to have more color choices. You would be the only vendor to offer that.Thank you for allowing me to test your SiGonna holders. I would rate this product 9.5 for the flexibility these holders provide.
