Love!
Color: Cream, Size: 2-Layer
I got this jewelry box for part of my girls’ Easter gift. They have been using them for about a month now. They love them! The size is perfect for my teens jewelry and helps them stay organized. They are really cute out on display on their dressers. Very functional, esthetically pleasing with the creamy white color, great quality for the price. Would recommend!
