Looks great, easy to assemble. Just a little narrow, wish I would have ordered a little bit bigger size.

Good purchase
Color: Gold, Color: Gold
It matches my decor and it was easy to assemble. I have been using it for the past month and so far it has done what’s it’s supposed to do, look pretty and hold the tissue roll in place. I am sure it will last years.

Good enough
Color: Black
It works but I find it gets pretty dirty on the bottom of it. I’m not sure how but I have to clean it every so often
