This clip prints without supports. It is designed to hold posters, papers, or other semi-stiff to stiff items on the wall without the use of nails or other damaging items. Apply to a wall using double-stick foam tape, sticky tack, or another non-damaging product on the side without the globes. Slip the item you want to hang into the opening and the globes will hold it secure. For larger items, use additional clips to distribute the weight. The gap in these clips are sized to fit a sheet of 92 lb paper covered in standard weight lamination film. These clips are perfect for home, office, or classroom use and making swapping out posters, artwork, and other display item super quick and easy.
