These stickers are printed on vinyl or washi sticker paper. These stickers can't be submersed in water. Stickers are handmade and made to order. Colors may vary slightly due to different screen settings. Due to the handmade nature of these stickers very small imperfections may occur. By ordering these stickers you are acknowledging you understand that. I do my best to minimize that as much as possible. For example some imperfections may occur in the cutting process but I do my best to make sure your order will be as perfect as possible! I don’t accept returns but please contact me here if you have an issues with your stickers.
