Cute idea in Theory, poor mechanics
The glasses are really cute to look at, but the mechanics behind them are not solid. The mechanics on 3 pairs of the 4 that I purchased have already broken. They stuck when pulled. Also, there is ZERO indication on the ordering website indicating that the eyes move by pulling on strings! So, when you put the glasses on and then you have to pull the strings connected to the glasses to make the eyelids blink, you end up pulling the glasses off of your face. Not the best design, and not enough information on the website to indicate what/how the mechanics of the glasses actually works.
