SHINKODASports Glasses Retainer Adjustable Sunglasses Strap/Lanyard, Pack of 2

El producto recibido fue tal cual lo descrito en el catalgo...

Works well. As advertised.

I wear dental loupes with magnification and they are very heavy. These seem to grip tighter than others I had bought.

I have an issue of glasses falling off when I look down and this completely fixes it. :D

First off I had this when I first got my glasses and wanted to branch out and try other eye glass landyards. Well, after trying over 5 others I now come back to this particular landyard, boy, am I - a happy camper, lol. I did take the adjustment knob off. I had to write an awesome review of this great item. Buy one and enjoy for yourself and if it doesn't work before the return deadline return it. Also, when the item is placed on glasses it DOES NOT want to slip off or even acts to fail in any way.

I liked them, but it was hard for me to untangle my hair

Por supuesto para los espejuelos en mi área de trabajo. Cómodos y Resistentes.

I needed these for holding my surgical loupes and they get the job done. The 4 stars is because if you are over enthusiastic, you can pull the nubbin right off and it’s hell to put it back.

Made in Chaina, This is not worth of the amount you are paying. Build quality is as good as chains product.Strongly recommend explore other products.
