Every kitchen needs one of these!!!
Color: Black, Color: Black
Whoever designed this is absolutely brilliant!! I have had so many sponge holders that either sit on the edge of the sink and make a big huge mess or they’re attached to the inside of the sink with suction cups and they fall off and they get in the way. This one is absolutely perfect. It has a little tray built-in on a slant so when you set your sponge or whatever in there, the water runs down back into the sink. No more water puddling on the sink running onto the counter. This drains it right back in the sink automatically I am thrilled with this sponge holder !! It’s a nice color and very well-made. It’s metal but the drain tray is a hard plastic , which is fantastic because then it won’t rust. I am all about making things in life easier and this sponge holder not only looks great , it will eliminate cleaning up messes off the side of the sink. I posted a picture with water running into the sponge holder and it shows how the water runs down into the sink… It holds various sizes of sponges. It’s got a little area for a brush .I have a couple of my smiley sponges ( no names mentioned ) that fit in there perfectly.. every kitchen should have one of these without a doubt!!!

Adequate sponge organizer
Color: Black, Color: Black
This is a black matte metal sponge organizer. It does have a tilted drip tray so the water drips down into your sink. The metal is cheap but effective. For the price, the added organization you get from this item is worth it! Could also be used in a bathroom. There is no mounting hardware included, not even adhesives.
The metal is already warped out of the box. This is not a high quality item, but the price is fair!
