Great Value For The Money
Color: White
I needed something to present my daughter's upcoming 18th birthday gift in. It's a charm bracelet and a bunch of individual meaningful charms. None of them come in gift boxes, and I want something to present them all together in. Failing to find a gift box to fit the bill, I thought that this cute jewelry box would be a nice alternative. I am pleasantly surprised at what I received for the price. I expected a flimsy cardboard-ish box, and this is not that. It's not heirloom quality, but it is a nice sturdy box, well put together, and the interior tray and dividers are thick. Interior fabric is nicely soft and velvety. The box is larger than I expected, it will hold a good amount of jewelry, and it's pretty and of much better quality than I anticipated. Will certainly make a very nice presentation for my daughter's gift, and she'll be able to use it for many years, I'm sure.

Not your average jewelry box....
Color: Sage Green
A lovely simple yet elegant jewelry box - nicely made with a practical design. It has substantial weight and opens and closes nicely. This sage green color is muted with a matte finish making it soft in appearance. The gold closure adds just the right amount of interest. I placed a beautiful pendant inside as a surprise and together, these made the perfect gift for a 40th birthday. Would buy again!

Elegant Jewelry Organizer
Color: White, Color: White
The jewelry box exudes an elegant appearance. I ordered white, but the actual jewelry box is cream-colored. Nevertheless, I am pleased with the various organized compartments and the two-tiered design inside. The box is truly stunning and complements my dresser beautifully. Giving four stars due to the Misleading color.
