A PEZ dispenser is a small piece of plastic where the stamp, the color, and the country make the price. A toy from a fast-food bag is the same pattern: bulk, and then a variant that is rare. In the overview Security for collectors it sits next to the surprise egg.
How it gets taken
In a box it is a toy. The one rare variant you put on top and photograph becomes a target among collectors, not among opportunistic offenders. You post the variant without the stack and without the room. It does not show up in the Radar.
What time does to it
Sun discolors plastic, especially white and red. Stickers come loose. A sealed bag you open is a loose figure afterward. You store dark and cool, without dispensers hooking into each other and the stamp rubbing off.
The folder
For the bulk, a box with the decade. For the rare ones, one line: variant, country, whether the sticker is original, proof. A photo of the stamp. Only when these lines add up to a sum you want to insure does the cabinet come into play.
