I have the same problem with Peppito! We have to be very inventive to try to hide the rolls in bags that Peppito cannot catch, but that remain convenient to use Our visitors are always surprised too! And even when I explain they have to hide the roll after use, some of them forget, and 5 min later I find a little mountain of teared paper on the floor. It is amazing how Peppito can quickly detect an accessible roll of paper!
I have been thinking of a metal box, but did not find yet something suitable
