Warm walnut organizer

For the price it's great I purchased this storage organizer for toys and it holds a lot of toys I filled one bin with trucks and they fit perfectly and in one I put books and the other some balls and had an extra cube for whatever I'd like to put in it. Although my organizer did come damaged, one of the boards had a chipping and a scratch, the delivery was very fast and great. I was able to assemble the organizer is 10 mins could get it done faster. Love the shelf would highly recommend

Very Nice Quality Storage Shelf with Bins.

I bought two of these in black. They are very nice. Great quality. Simple to build, my teenager built them both in 20 minutes. I bought them for storage in my kitchen. The pair sit side by side, beneath the kitchen window. Not only are they great storage for bottles of water and lesser used appliances, but it is also a wonderful plant stand. Although, I didn't use the storage bins with the shelves, they are helpful throughout the rest of my home. I am very happy with the shelves; they look so good and tidies up the area.
