Liked it so much I bought a second one
Color: Grey
Good quality….a little disappointed I thought the sections were stationary, however I’m able to move them to accommodate the chain size. Clear color and light weight. Fits in with my decor. I ended up buying g a second one I liked it so much!

Dividers don’’t stay in place
Color: Beige
The dividers do not stay in place. It’s a great idea but not well executed because the dividers pop up or slide, leaving the necklaces to get tangled.

Slots inside drawers are not tight enough.
Color: Grey
I got an earring storage bin that matches this one and I do like this storage drawer set, but the little slots that separate the necklaces move around too easily and I don’t like that. It looks classy with the other stack I have.

Great Tray For Storing My Everyday Carries
Size: 8.5" x 5.8" x 1.9", Color: Black
My everyday carry items (wallet, keys, etc.), used to just get thrown around wherever when I'd get home, but this little tray makes a great, defined, space for me to keep those things when I don't need them on me. The soft lining reduces the obnoxious sound of throwing keys on a hard surface, and of course keeps me from scratching up a surface. The build feels quality and I haven't seen any damage to it yet. Also the all black version with gold buckle looks quite good and adds a subtle touch of luxury. Absolute recommend for the price.
