It’s Okay—Does the Job, But Not the Sturdiest
Color: Black
This paper towel holder is fine for what it is—it holds the roll and looks decent on the counter. It gets the job done, but it’s not the most sturdy. When I tear off a sheet, the whole thing sometimes moves or wobbles unless I hold it down. It’s affordable and works in a pinch, but if you’re looking for something solid and heavy-duty, this might not be the best pick.
