These tabs are reusable so you can remove them and reposition them without leaving any residue. The lost adhesive quality of the tabs can be restored afterwards by cleaning them with warm soapy water. These tabs can be used to mount cards, photos, posters and more. There are 18 tabs in this pack so you can stock up at once. These tabs are pre-cut and measure 25.4 x 25.4 mm. These tabs are also reusable and can be restored to their original condition by washing them with warm soapy water. These tabs will securely hold your photos in place but are removable so that you can reposition them. These tabs are great alternative options to magnets, tacks, screws and putties. These are double-sided with quality adhesive on both sides. These tabs are clear so that they remain invisible once in use.
