Easy and Quick Install These UPC label holders are easy and very quick to install. Simply clip them onto your wood shelf display and insert a label into the channel. You can also apply an adhesive label to the holder as well. The labels slide right into the label holder and the label holder protects the label so that it doesn't fall out. Professional Looking Use these label holders as a convenient and professional way to draw attention to your product information. They help keep your retail shelf tags looking neat and helps keep your inventory looking organized. Won't damage your shelves The label holders are made of non-marring plastic and won't damage or scratch your shelving. Use these label holders instead of sticking labels directly onto your shelf. This makes it easier to move the labels around should the need to move your inventory arises.
