The sticker: In two sizes. The smaller, which is ideal for laptops, has a "permanent" adhesive, which means that it's hard to peel off. When you do, it will leave some adhesive behind, but that's easy to remove with Goo Gone or similar.
The larger one is removable and especially well suited to bumpers.
Here's the printer's explanation of the difference between the two, the smaller ("die-cut sticker") and larger ("bumper sticker"):
All of our stickers are printed on premium vinyl with a permanent adhesive. They are coated with a protective laminate that makes them resistant to fading, scratching, tearing, and water. They can even be safely run through a dishwasher. That said, the main difference between our die-cut stickers and bumper stickers is the adhesive. Bumper stickers have a low-tack adhesive that’s designed to be kind to car paint as well as be easy to remove. Permanent stickers may leave some residue when removed, but it’s easily cleaned up with some soap and water.
Both are printed in the US on thick, durable vinyl with a UV laminate that protects the sticker from scratching, rain, and sunlight. Die-cut. Includes the silhouette of Ben Franklin.
