The PUKPUK JELLY stickers featuring sea creatures seem to glow in the dark. They faintly illuminate when it's dark. These are Little Twin Stars crystal stickers. Both were purchased in-store. I've collected too many stickers, so I'm putting them up for sale. I'm also selling other stickers, so I can offer a combined discount. - Brand: Little Twin Stars - Quantity: 15 sheets - Design: Crystal Stickers - Theme: Sea Creatures - Style: PUKPUK JELLY Thank you for looking.
