Bugs... that last one you listed the site direct, is the one we had.
The problem was, everyone would put their wet drippy hands on the top knob, and drip all the whatever was on their hands, all over the roll of towels.
What I did, is I took a round 8 inch plastic top from a tupperware container, and I cut a hole in the middle tight enough to cover the roll of towels. That saved the roll from getting wet.
Tina said it looked like a roll of towels in a auto repair shop. hahahahahaha
Oh! I did bring home a brand new paper towel holder, all chrome, from an office building that the building tech gave me. I mounted that, and filled it with the folded light brown unbleached paper towels. Tina said,"NO NO....get that G D thing out of here!" "That thing belongs in a roadside rest stop, and not in my D House!"
I said, "But it's brand new, and has a lock with a key to open it!"
I thought it was unique! Tina almost cried!.
