These clips can be printed without any support required. They are designed to hang posters, papers, or other semi-rigid to rigid items on walls without the need for nails or other methods that could damage the items. Attach them to the side without spheres using double-sided foam tape, adhesive tape, or other types of tape that will not damage the products. Slide the item you wish to hang into the opening, and the sphere will securely hold it in place. For larger items, additional clips can be used to distribute the weight. The gap size of these clips is suitable for a 92-pound sheet of paper coated with standard-weight laminate film. These clips are ideal for use at home, in offices, or classrooms, making it fast and easy to replace posters, artworks, and other display items.
