I’ve tried so many and Love this one!
Color: Black, Size: Large (10"W*6.69"D*2.17"H)
When I travel my earrings and broaches and bracelets are important parts of my outfits (I like finishing “the look” with the right accessory or two. I’ve struggled to find a good, accommodating yet packable case. This has a very low profile which makes it very easy to slip in my luggage. Well made, sturdy and good zipper It holds lots of earrings and underneath will hold my broaches. Room left over in lid for bracelets and a zippered pocket for additional storage. I found exactly what I wanted and needed in this case. Highly recommend.

Just Buy it!
Color: Black, Size: Large (10"W*6.69"D*2.17"H)
I purchased one of these for my mom for Christmas and I loved the quality so much that I purchased another one for myself. I always have all these different jewelry bags when I would travel and it was annoying. But now all my jewelry is together in one place. The quality is really great! It’s durable and big enough to fit many shapes and sizes of my jewelry pieces. The best part is that the middle part can be removed if you want. It’s really cute and chic. I’m so glad I purchased this jewelry case.
