Our Self-cling Stickers have a superpower. Their miraculous ability to cling to very smooth surfaces without adhesive, our self-cling stickers have a legendary status in the world of promotional graphics. Using static to adhere to very smooth surfaces such as glass, our self-cling stickers are available in white and clear. Clear clings are printed in reverse and backed in white, whilst white clings are printed straight up. The white clings can cling by the front and the back, and unlike most other superheroes, do not require an assistant.
