We suggest you buy 4 stickers or even more: Enjoy much lower unit price. As a spare sticker when the paste fails. Post in various places such as your car, wall, door, refrigerator, toilet and so on Give extra stickers as gifts for friends and family. We use eco solvent 140g bubble free gray adhesive removable vinyl sticker to print. Most other stickers use 80G or 120G and it is not bubble free material. Bubble inside Color Fading Non-removable adhesive Three Ratels sticker is a removable adhesive, and when you want to change different sticker and you can remove it easily. You don't need a hair dryer and you didn't leave any glue in your car. Keep for 4 years without color fading and no material bubbles. The magnetic sticker is popular in the market. I advise you not to buy because it is not stable like glue and also may hurt your car paint
