Unsure
The product looks fine, no damages or such, but they did not solve the problem I bought them for.  I bought them with hopes of keeping my glasses from slipping down my nose and also stop the pain the glasses was giving me sitting on my nose without cushion, but unfortunately the pads didn't really work, as I found myself still having to push my glasses up on my nose and still having pain on my nose.  Will have to try something else.
