Love Lab 3D Glow-in-the-Dark Stickers, Puffy Stickers Set of 2 Purchased from an overseas website. These are glow-in-the-dark stickers, so they will glow in the dark after being exposed to sunlight. Not all of them glow; some, like the second image, will glow. Please consider this as a reference. These are overseas products, so there may be printing errors, folded backing sheets, variations in the adhesive, and stains. When shipping, the backing sheet of the stickers may bend slightly, but please purchase only if you understand this. Please refrain from purchasing if you are sensitive to these issues. m(_ _)m
