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. .
