These plastic hanging tabs can be stuck on the back of our iron on patches to easily display them vertically on grid walls or slat walls. Each tab measures 1.5 inches by 1.7 inches. They come in sheets with 20 tabs. This makes peeling them off easier and faster than using tabs that have individual backings on them. We sell them by the sheet. Try them, you'll love them. Please note these tabs will work for patches with plastic backings. All patches we sell (with the exception of blanks) feature plastic iron on backings. If you were intending to hang cloth backing patches with these peel and stick tabs we don't recommend them.
