Beautiful and Functional - And A Great Price. Just Bought My Third One
Color: Beige
I just ordered my third Sumnacon square linen tissue box cover. This tissue box looks just like linen - but it's better because unlike real linene, it can be wiped down and cleaned. It is a soft linen color... it blends beautifully into any decor. Such an improvement over a cardboard tissue box. I got one for my bathroom, then ordered one for our bedroom. I just ordered another for the kids bathroom. It has a magnetic bottom which is great and the price is right. I've purchased big clunky ceramic tissue box covers in the past and these are far superior. Understated and very pretty.

Attractive & Practical
Color: Beige
Great quality tissue box cover. Solved a big problem. PU with a linen weave texture. Attractive finish. Weighty, magnetic bottom and a great fix for the tissues box falling into the floor every time a tissue is pulled. Solves a lot of issues.

Elevates your tissue box
Color: Beige
Very well made! Sturdy with nice look. The fabric can easily be wiped down if needed. Very pleased. The tissue box slides easily in and I like how the bottom is covered as well. Elevates the box for any room. Great value for the money! Bought two and plan to purchase another.

Super Cute and Hides Ugly Tissue Boxes Perfectly!
Color: Beige
Absolutely love this tissue box cover! It’s super cute and matches our house decor perfectly. It makes such a big difference compared to looking at regular tissue boxes sitting out. The quality is nice, it fits well, and it’s a simple way to make the room look more put together while hiding the ugly tissue boxes. Definitely happy with this purchase!
