Chic Storage Solution!
Size: 10 Slots, Style: 1 Layer, Color: Beige, Size: 10 Slots, Style: 1 Layer, Color: Beige
LOVE this. I needed something to keep my sunglasses together. Why I have this many sunglasses is my business. Lol but this box is beautiful and soft inner and the outside is like a soft faux leather. The color is beautiful. I have one with 10 slots and its perfect for my wide brim Quay Sunglasses and my Gucci Glasses. I also included these Quay Dupes I found on Amazon in my box. It's just a perfect and chic storage container for my sunglasses.
