Double-sided tape is any pressure-sensitive tape that is coated with adhesive on both sides. It is designed to stick two surfaces together, often in a way which is not visible in the end product, due to it being in between the objects rather than overlaying them. This allows for neater-looking projects and better craftsmanship. Double-sided tape can be either thin or dimensional. Dimensional tape is thicker, and is of particular use to retail and signage uses where it can be used to allow signs or displays to stand out with a 3-D effect.
