TSV 2pcs Adjustable Glasses Straps, Eyeglass String Holders, Silicone Eyewear Retainers, Black

If you have a big head it will be a close fit. The cord could be half inch longer. It fits narrow arms. Wide frame arms would not work with this product.

They work good.

excellent product, dont know what I would do without it

i get these for my 6 year old son and they are wonderful! they are adjustable and great quality!

This worked out perfect for me. I almost ruined them because I thought they were too short but that's because I didn't know that I could extend them. The end of the arm that goes behind my ear had worn out. These were able to provide me a cushion when putting on my glasses.

Awesome just as depicted in ad

So, maybe it's the shape of my head….. or the style of glasses I wear…. But these just didn't work for me. I mean, they seem to be very strong and somewhat flexible. But very stiff also. It's a neat design, but just not for me. Nothing against the item itself. Just being clear.

Need to be about 4 inches longer. They are small

Too short they are not for adult!!

They don't fit on the glasses. I tried to return them to the local store and was told they can't take returns without the item being in a sealed package. This item is not shipped in a sealed package and not in a package box. The items was only in a Post Office shipping bag.
