Amazing Jewelry Travel Case
I bought this jewelry case for traveling on a cruise and I absolutely LOVE IT! When I purchased it I didn’t know if it would actually fit all the jewelry I wanted to bring but this box definitely impressed me! It fit all my regular jewelry plus more bc you know us woman love to coordinate with our outfits lol the case/box is sturdy! It didn’t break or even dent throughout my travels. It comes with different pieces to help organize and separate jewelry but it is removable if needed which I had to do bc one of my necklaces is really big. The case fit perfectly in my carry on luggage and didn’t take up much room at all which helped me a lot. I got the black case and I just love how simple and sleek it looks. This is definitely a must have if you need to travel with jewelry and are concerned about things getting damaged, this case keeps them safe and it’s definitely a great value for your money!

Perfect!! I’m obsessed!
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Beige
So cute and great for travel! Lots of organization areas, easy to use, very durable and not made cheap, the zipper closes just fine and it’s compact for traveling or storing under the sink.
