Prefect Travel Case
Color: Black, Color: Black
I got this for taking my jewelry on the go. I have to say that I was pleasantly surprised by the quality it feels very sturdy. It has several spots to hold jewelry and keep it organized. The outside is textured and it closes with a snap which can be done easily.

Small, bu holds a lot
Color: Black
I initially purchased the Jewelry Box Necklace Ring Storage Organizer as a gift for my 8-year-old daughter. The compact design and practical features seemed perfect for her little trinkets. However, its quality and style so took me upon receiving it, I decided to keep it for myself! The jewelry box is small, but it holds a lot with a double-layer structure that provides ample storage space for various types of jewelry. It easily accommodates rings, necklaces, and other small accessories without clutter. One of the highlights of this product is its portability. Its compact size makes it an ideal travel companion. I've taken it on several trips, and it has proven incredibly convenient. It keeps all my jewelry neatly organized and easy to find, eliminating the hassle of untangling necklaces or searching for a matching earring.

I didn’t receive the item and I let Amazon know the item was not delivered. Apparently, they don’t care to follow up with my lost order. Hummm, I wonder how the owner of Amazon would solve this problem.

Closing it when you have a ring.
Color: Black, Color: Black
Its a nice box but the problem i have with it is the middle piece. It does not give enough room if you have a ring that sits high like a cocktail ring. And same if you have a pendant necklace in the necklace area. You have ro really force it closed and i worry that it will put pressure on the items. It would work better without that middle piece for earrings or maybe if it were half the size. Closes fine when its empty but the minute you put a ring in the ring spot that has any kind of height you have to squeeze it shut. Its a good little box that you can put in a safe. Thats why i use it. Just to put my good jewelry in it and then secure it properly in a small house safe. Also ive already had the backs of a few earring pop off when I've opened the earring flap because it all rubs together. .
