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.

I like these helped me organize my mess
Color: Brown-2 Set
I bought the two pack of these to organize a drawer with a bunch of my stuff that was just too cluttered for my liking. I may be mildly ocd. They really improved things. They seem to be decent quality. I consider them to be a good value for the money. They function well for my use and also look good.
