Stickers featuring a Hopkinsville goblin hiding behind a gem, and a mimic monster in an electric rat costume :)
The stickers come in regular colors of the purple goblin and yellow mimic, and "shiny" holographic color variations of the green goblin and gray mimic.
Stickers are made in my home studio. They are print with dye-based inkjet on glossy vinyl sticker paper, then cut with a silhouette machine. The shiny holographic stickers have an additional transparent overlay. Each sticker is approximately 2.5 inches large, slightly water resistant, and recommended for indoor use.
