I use this as a "catchall". A place to stash things like my wallet and keys when I enter the door, so that I don't use them (I had been prone to that!). It serves it's purpose well. It's both sturdy and attractive, and a good size for a "catchall". Recommended for those like me who need such things.

Color looks great, material is good quality and fits most of my items. It makes my items look neat and organized. Price is a bit high but worth it in my opinion.
