Functional Design & Compatibility: Crafted with a snap lock closure, these plastic label holders are designed to snugly fit on varieties of wire shelves. They're durable and strong, made to last, as the top clip securely locks into place, ensuring they don't fall off unless intentionally removed. Versatile Use: Perfect for applications in supermarkets, grocery stores, shopping malls, pantries, warehouses and any other establishment making use of wire shelves. They're excellent for displaying prices, marking unique UPCs, special offers, or identifying stocked products and inventory location markers. Optimal Size: The holders measure 3inch Long and approximately 1.5inch Tall, excluding the top clip. They're designed to hold cards up to 1.25inch tall and perfectly 3inch long. You can even insert longer cards - they'll extend beyond the holder but will remain securely in place. Labels can be easily applied and removed without leaving a residue. Effortless Application and Removal: The clip on top neatly attaches to any area or shelf. Slide your card into the holder or directly apply the label. For relocation, simply unclip, then reapply at the new spot. The labels or cards can always be easily replaced without causing the holder to fall or leaving a mess.
