Seller: matthewd4433 (346) 100%, Location: Mooresville, North Carolina, Ships to: US & many other countries, Item: 223628081841 This listing is for 100 NEW clear glass cat eye sign reflectors. They measure just a hair over 3/8” in diameter and due to the nature of the molds this can vary ever so slightly from reflector to reflector. Please see photos to review dimensions. They are all glass with a gold reflector paint on the base. They shine up great and clear! These are the smallest reflectors I currently offer and I have included a photo for you to compare their size to my 1/2” and 11/16” ones. They can work as a replacement for old reflectors of comparable size but you likely need a grommet and/or an adhesive to secure. ( Grommets available to purchase separately since not all projects require them) Old reflectors had wide rims & mounting cups and the grommet + adhesive replicates that easiest. Tighter fits and holes drilled specially for the reflectors may be able to secure with just adhesive/ silicone. If your project requires more reflectors or a combo of sizes/colors don't hesitate to reach out for a custom listing to save on shipping costs!
