After teasing it last week, today Creepy Co. launched the next enamel pin in their GPK collection. The Halloween themed pin is based off of #153a/b Jack O. Lantern/Duncan Pumpkin card from OS 4. The pin can be purchased from their online store for $11.99 + shipping. This pin adds to the other five pins from their Wave 1 GPK release. Creepy Co. is continuing to sell the other GPK pins, buttons, and puffy stickers on their website. You can expect more GPK items in the future from Creepy Co., as they utilize their license with Topps.
