All my items fit perfectly for my girls trip. It holds a lot of jewelry, the zipper quality is very good, and it’s soft in the inside and the outside. It was so good I also purchased some for the other ladies to take on the trip.

Great sized, nice organization, lacks protection for studs
Color: White, Size: Medium (8.46"W*5.71"D*2.17"H)
The size is great. I love that it zips closed
I don't need as much ring storage as it has, and I could use some larger compartments for earrings
My biggest complaint is that the flap that houses the studs doesn't have any extra space, so the stud earrings lay directly on the rings. Not great for protecting metal and stones from scratches and bending.
