Keeps the Sink Area Neat and Organized
This has been really helpful for keeping my sink area clean. The soap dispenser pumps great! The sponge and brush holders keep everything off the counter so that really helps.
The stainless steel looks nice and hasn’t shown any rust so far. It’s compact but holds everything I use daily, and cleaning it is easy. Great little upgrade if your sink area always feels messy.
edited to add: took me about 45 minutes to finally get the sticker label off it was stuck directly on the stainless steel so I had to be really careful peelng it off

Stainless Steel 3-in-1 Sponge/Brush Holder with soap dispenser for Kitchen
This is an ideal item to organize your sink areas. Perfect for kichens but also for bathroom use. I love the built in soap dispenser. The one I currently have doesn't have a dispenser. And the big liquid soap container is always falling over. Mine irack is bigger but this one is more organied.
Easy to clean. stainless steel. Smaller foot print so it sits right near the faucet easily. 7.3"L x 5.3"W x 6.5"H And, it has drainage holes in the front rack to keep your sponges fresh by quickly drying. I was going to put this in one of our smaller kitchens in a guest house, but I may just snag it for my kitchen!
Good value. Priced right.

Sticky wicket!!
This product arrived as described with one exception. There is a label on the front with a sheer plastic covering
which mostly comes off, however the paper and adhesive remaining defy every solvent known to man!!!
It has been soaked (twice) in Goo Gone, twice in rubbing alcohol, once in stainless steel cleaner and three times
in Dawn power wash.....It remains.... I'd go after it with a razor blade, but I don't want to scratch the stainless.
