The all emcompassing stick all wonder
goo. Saves you from explaining to
landlords, can also serve as
silly putty in a pinch.
typically used to stick posters to walls, but can also be used to hold small objects down. remains sticky for an alarmingly long time..
The brand name version (possibly all versions, I am not sure as it has been a long time since i had to buy more, my ball is still sticky) is BluTack.
Manufacturer is Bostik. Comes in flat cardboard packages. Best way to remove is roll,roll,roll.
