Love my wire baskets!
Color: Black
I am in love with these baskets. My kitchen is quite tight and I needed more counter space. These were a perfect solution for my problem and exactly as pictured. You can label as you wish and change anytime as it comes with three different colors of chalk. I feel as though these would complement an array of kitchen styles. They are extremely sturdy and easy to install. Highly recommend if you’re in the market for storage or organizing solutions!

Great for guest towels
I needed hanging wall baskets for guest towels in our powder room. Especially during covid times, I wanted our one friend who visits to be able to use a fresh towel every time she arrives, as proper hand washing is extra important. I didn’t want to use paper towels.
These are the first ones I found that seemed like they might be workable. I love them!
They seem to be well made little baskets, and they are easy to install. Friend likes it a lot too.
I have one basket left, and there are so many possibilities. The size is just big enough, without being huge or sticking out too far. The gold color is gold, not rose gold, not yellow, just gold. There are no sharp edges or anything sticking out for towels to get caught on. The signs are premounted frames with little chalkboards that you simply side in. Chalk is included. Very nice, I’m happy.
