What are polycaps by the way?
Polycaps are hard rubbery pieces ussually used in joints and connectors on gunpla. They come on a extra PC runner not labeled ABCD 123 etc
Yeah they're typically softer rubbery plastic things.They're nice on smaller kits but they can wear out too, which can be a nuisance.
Even now in the glorious days of SDCS and figure rise Satan still finds a way to return.
