Love it!
Size: 24 inch (Black), Size: 24 inch (Black)
Great rustic looking towel bar, compared to the price of actually buying the bar at the hardware store and making it! It’s also actually metal, compared yo some that are plastic made to look like metal.

Simple, sturdy and strong.
My spouse wanted this to mount above our kitchen window to hang plants. As much as I could absolutely care less about looks and design, this did look really cool and works great. It’s made of good strong quality metal and has everything you need to mount it.
