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!

Slim, Stylish, and Perfect for Keeping Counters Organized
Size: B 1PCS, Color: Black
I love the slim, compact size of this organizer. It takes up much less counter space while still offering the perfect amount of compartmentalization for keeping everything neat and easy to find. The material is a big plus since it won’t rust, and it looks really nice on my countertop. It definitely helps my counter look less cluttered and more organized. Overall, a great functional and attractive storage solution.
