Well made and perfect for the drop down table in between our two recliners in our couch. Holds all four of our remotes. Tissues come out easily and are easy to put into the holder as well. Looks very fancy. Great value for the money.

Beautiful and well made
Color: Rectangular Tissue Box-retro
Such a beautiful and well made kleenex box. I absolutely love mine. I ordered 2 more after receiving my 1st one for my office. Easy to get the box in. Looks so nice and the kleenex feeds out of it easily. I even ordered my parents one for their office as a gift.

Very Pretty and Nice Addition to my Living Room
Color: Square Tissue Box-retro
These look nice and were reasonably priced. Putting my tissue boxes in these holders also stopped my dog from tearing up boxes of tissues (he likes to tear up paper). he has not bothers these. They help the tissues blend into the decor without the distractions of the funky colors on the cardboard boxes.
