My new kitchen favorite!!! Looks just like picture!

Love this, looks just like picture. Fits perfect by my sink and the drain spout positions right into sink. Holds quite a few things. A kitchen must have! Well made, stays put, easy to rinse when needed and my room mate loved it too!

Great sink organizer
Color: 1 Tier-Black, Color: 1 Tier-Black
I've been searching seems like forever for something to make my kitchen sink look more organized and this caddy solves my problem!! I found a different use for the basket that holds a scrub brush since I don't use one of those. Nice design that fits my kitchen objects and no worries about removing a tray to empty water out. I used the adhesive holder to attach it to the wall behind the sink but one corner is peeling off, causing the basket to hand on that side. :( It would have been nice to have a replacement for that, but overall I'm pretty impressed with this thing!!

Nice Product

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.
