Return for a reason
Size: Paper Towel Holder - Standard Design
The spray bottle feels very cheap, and it doesn’t stick well down to the paper towel holder. The actual holder is an OK quality it’s very flimsy but it does the job. I would recommend to spend the extra money to get a better one from amazon

I absolutely love this paper towel holder! It’s not only sturdy and sleek, but the built-in spray bottle is such a clever and practical idea. It saves me space on my countertop and makes cleaning super convenient. The base is heavy enough to keep it stable, and it holds the rolls perfectly. Definitely a great addition to my kitchen — stylish and functional at the same time. Highly recommend
