Something I never knew I needed, and now can’t live without!
Color: Black, Size: Large, Color: Black, Size: Large
Absolutely perfect, high quality organizer. I was constantly reaching under the kitchen cupboards for sponges and drain stoppers which then cluttered up the sink while letting them dry before putting away. I love the size and option to put the basket on the outside edge for more space. It holds everything I need. I especially like the stone underneath so I can place it anywhere and not have to worry about a drain spout. Keeps my sink and counters clean and organized and looks great in my kitchen.

Best kitchen caddy!
Color: Black, Size: Large
This is the best kitchen caddy. It works well on the edge of my sink. It's a little bigger than I thought. My measurements were off, not there's. I propped up one side and it works beautifully. It holds all the sponges, soap, and cleaning utensils needed to clean your dishes. Now my kitchen sink is clutter-free. It also looks great!
