These are a good choice
Color: Black-2 Set
These are great. They are made well, look nice and are easy to move when I’m dusting. I use these to keep perfumes, lotions and vitamins organized atop my dresser. The velvety compartments are a well sized and the layout is conducive to storing the kind of objects women or men typically store atop a dresser. I find these bins quite functional. I feel like these were a good value. They weren’t the cheapest and they weren’t the most expensive. They look nice and feel high quality enough.

Nice and works great in my nightstand
Color: Beige
Smaller than I expected, but good quality and looks nice in my nightstand drawer. It will keep things from rolling around. Seems sturdy and I like the pinkish undertone to the beige.

Great end table organizer, Style, size, cost
Color: Brown-2 Set
Good size, very useful tray. The large compartments are laid out well. Small areas good to hold a watch, change, lip balm, etc. Affordable price and made well, looks more expensive. Keeps "stuff" neat and clean.
