These two pins are from Hazbin Hotel, an American online animation that attracts a large number of fans with its unique dark fantasy style and rich character settings.
These are two stained glass hard enamel pins. Stained glass is injected into the metal block in a hollow form, so that the paint surface texture and the metal are integrated to form a unique transparent texture block, which increases the layering and three-dimensional sense of the pin. Combined with hard enamel, it can integrate the advantages of both and improve the quality of the pin.
