Been using this thing for over a year now and it is fantastic. The color is beautiful and as described. The price was a very good price point. The size is everything you need it to be because it’s nice and sturdy; it holds a big Costco size roll. And the roll actually fits over the top. You don’t have to unscrew it. In love.

Stylish and sturdy paper towel holder

Color: Gold Polished

This gold paper towel holder looks great on my counter and works perfectly. The base is nice and heavy keeping it sturdy, which keeps it from sliding or tipping when I pull off a paper towel. I’ve had no issues with the roll coming loose or falling off, even when grabbing sheets quickly. It’s both functional and elegant. Gives you good value for the money. Definitely worth it if you want something that looks good and stays in place.
