How many times have you reached to pull a sheet a paper towel and you get the whole roll to come with it or the holder tips over? How frustrating!! With the MOBI Paper Towel Holder, you have the security of a suction cup at the bottom to keep the holder in place. A simple twist of the knob engages the suction and another twist dis-engages it. Simple. Attach the holder to your tile, stone or stainless counter-tops or even to smooth surface walls and you’ll see what one hand operation is really all about.
