Great for organizing sink
Color: White - 9.25″
We had one of those suction cup sponge holders, but if you have tile that is not completely smooth, it falls down. This does not have that issue because it just sits on the counter or if you have a large sink lip, on there. You can move the inside pieces around which I was really surprised about because I thought it was all in one piece. Being able to move them around is great because then you can adjust it for your own soap dispensers, etc to fit your space. I like that it comes in a ton of colors. We got the white and it blends into our kitchen and looks really nice. This organizes our dish soap, sink drain cover, and sponges nicely and gives it all a space to go in. The tray on the bottom is silicon and removable which is great. I wish I had bought this thing years ago because it's great.

Nice set of kitchen brushes!
Color: Yellow, Color: Yellow
These were just what I was looking for to be able to clean a variety of items. The long handle is great for jars and tumblers. The wood handles are attractive and compliment each other nicely. The handles feel sturdy and well made while the bristles are flexible and soft enough not to scratch the non stick cookware.
