A post should contain one or more of these tags to indicate if a pin is interactive or not:
single_piece: The most standard kind of pin. One piece of enamel. (not to be confused with the anime one_piece)
multi_piece: Pins that consist of multiple pieces of enamel.
magnetic_pin: Pins that involve usage of a magnet. For example, two pieces of enamel might be magnetically joined to create a pin with a removable shirt.
spinner_pin: Pins that have a part that is able to spin freely or mostly freely.
slider_pin: Pins that have a part that is able to slide along a track.
spring_pin: Pins that have a compressable and movable spring included to move part of the pin.
fluorescent_pin: Pins that fluoresce under UV light. These pins do not necessarily "glow".
glow_pin: Pins that glow in the dark after exposure to regular light. These pins are usually fluorescent as well.
