The holders are the best product I have purchased this year! I study and work with my glasses on more than 75% of the time, throughout my day. This has helped me tremendously by not misplacing my glasses. In addition, I can just quickly take them on and off when I need to without the hassle of where I need to place them. Furthermore, they are very stylish and match with my day to day wear, I love it!. I gave my daughter one and she simply loves it too! My sister is also ordering this product andSee full review
