Great little sink organizer!
Color: Black
This is a lovely addition to my kitchen sink to handle all of my dishwashing tools. And I really like the DE base to catch all the drips and water drainage. The separator in the middle is moveable so you can determine how big or small you want the partitions. It was packaged very nicely and came with stick on feet to protect your countertops or sink edge. Highly recommend if you were looking for something this functional.

Nice Product
Color: 2 Tier-Black, Color: 2 Tier-Black
Super Handy and So Stylish — A Must-Have for Any Kitchen! I’m really impressed with the Sinnsally Kitchen Sponge Holder! It’s simple, practical, and makes keeping my sink area neat so much easier. The 2-tier design is brilliant — the top shelf holds my sponges perfectly, while the bottom area keeps scrubbers and brushes organized and easily accessible. The stainless steel looks sleek and modern, and it has held up beautifully with daily use. Water drains well so everything dries quickly, and cleanup is a breeze. No more soggy sponges sitting around! Installation was quick and easy — it fits nicely right by the sink without taking up too much space. This little holder has made a big difference in keeping my kitchen tidy. Highly recommend for anyone who wants a clean, organized sink area with a touch of style!

Great space saver
Color: 2 Tier-Black
I love how this makes my sink so much more organized. For me, it holds a 20oz dish soap, a dish spray, 2 S.O.S. pads, 2 sponges, a steel wool scrubber, a bottle brush, a Stanley cap cleaner, and a sink stopper. I could still fit more if I wanted to. I can move the tall brush holder to whichever side I want, as well as the divider. It was super easy to put together, and functions well by draining all the drips right into my sink, instead of behind it. The black looks great and matches my kitchen well. This organized is built well and keeps mynsink area tidy and hygienic.

It Looks Nice and It Works
Color: 1 Tier-Black
I like it. It is too long for my sink area, but it still works. Next to my sink is a dish rack. One half of the caddy fits perfectly behind it, holding a 16oz bottle of dish soap and a 16oz bottle of multi-surface cleaner. The part of the caddy that fits on my sink ledge holds a sponge, scrubber and scouring pad, The caddy works great at keeping the ledge dry. It is a very nice, well-designed item. I recommend this caddy it's keeps everything organized and dry.
