The original and famous "mineral tack". While it resembles ordinary "sticky tack" used for hanging posters, this is a special easy to remove formulation that is chemically inert, non-hardening, non-greasy, non-staining, and leaves absolutely no residue on your specimens. There is a reason museum curators and mineral collectors the world over use this putty to secure their specimens to their displays.
