Works great
Color: Square Tissue Box-retro
I bought this to prevent our puppy from chewing up the Kleenex boxes. Worked like a charm and looks good too. Not flimsy, nice quality.

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.

Like it so much. I've got a second one
Color: Square Tissue Box-retro
Liked it so much. I've got a second one. This tissue box cover is so elegant and beautiful that I bought another one. The bottom snaps in place very nice and the threading around the box is beautifully done. The brown color goes very well with all of our oil rub bronze pictures in the house. It is very elegant and I just love it.
