The cheap reading glasses so far have been made of plastics many times, and cracks (breakage) due to aging have always occurred. It was destroyed for about a month in the early days and it went to the trash box.
This product is soft material is used, there is no worry about that. It is optimal as a sub and it can be handled somewhat roughly without problems.
There is no problem even if attached for a long time without feeling to tighten the feeling of hanging, the lens is also good, I just bought only one so it may be only my amount But when one of the vines is placed on the desk 5 mm It seems that it is leaning a bit when looking in the mirror, because the price is cheap, this distortion may be useless,
Is it the length of a vine? I feel the R position of the ear is short. Because it is individual difference, there is no use. It seems like a bad thing because the hair (long) will come about the slippage part of the slip. Design & color scheme is good feeling!
