The mask is beautiful! I have not yet attached it to my glasses, but have held it up exactly where it will go and the mask looks like it will work well. My only wish is that the mask was available in colors other than black. With hair that is not blonde, part of the decorative mask literally disappears (the detailed butterfly which comes up past my forehead is virtually invisible). My guess is that for people with blonde hair this would not be an issue. Assuming the mask attaches to my glasses the way the video describes, the design is brilliant (especially if your glasses aren't too wide) and this is the only mask anything like this that I could find online. Thank you for this wonderful option!
