Minimalist elegant, yet sturdy
Color: Gold-b, Color: Gold-b
I love the clean, minimalist design, it looks modern and elegant in my kitchen. The holder is solid and well-weighted, making it easy to tear paper towels without sliding. I’ve been using this for nearly a year, and it still looks and works like new. Great quality, good value for money.

Beautiful & Great Price!
Color: Gold-b, Color: Gold-b
I was looking at a $60 Williams & Sonoma “honeycomb collection” marble paper towel holder with gold bee accents, but decided to save a bunch of money and go with this one.
Glad I did! It’s awesome!!! Easy to put together with the wrench that’s included, it’s packed well - great product for the price and they sent a free gift with it too. Received 3 super soft dish cloths along with the paper town holder. Unexpected surprise and happy with them too!!
Just placed an oder for another one for the other bathroom sink. This will not be in a high use area so I’m not worried about the base getting beat up. I feel like it’s just the right weight. Not as heavy as real marble, but heavy enough to hold the towels securely. The gold is a pretty shade.

Heavy marble base and solid rod holder.
Color: White-aa, Color: White-aa
After researching the many different marble base towel holders, which is what I wanted to match my marble decor, I finally settled on this which arrived today, packed very nicely in a Styrofoam tight box to protect the marble and came with it as you can see a gift of some very soft Microfiber dish cloths, which work very well at removing smudge marks on kitchen appliances. It took me 30 seconds to join the base to the rod. It came with a little tool to tighten the base however it really wasn’t necessary. I then covered the hole under the base with a piece of One-sided circular sticky, felt, which covered the hole very nicely. I have tried it, and it does do as it says, and the marble base is heavy enough where it holds the roll of paper towels so that with a couple of tugs, I can get one of the perforated sections out. Does take more than one tug as some people showed but two tugs or three light ones really doesn’t matter it gets the job done and in a far lower price than any of the others, in fact, some of the recommended others were 2 1/2 times more expensive and the reviews were not good at all. It pays to take the time to go through people’s reviews like mine and that’s why I believe in completing the reviews whenever I can time permitting. I’m giving this a five star and I think that you will too. I was lucky based on some of the other marble bases that were shown for this product that I got a significant amount of gray marbling matter because some of them had very little it’s just the way the marble runs and you take your chance, but I was lucky.
