Check the listing for details. Rectangular Universal Charm/Keychain Base. Condition: New. Listed at 5.99 USD. *FOR AIRSOFT USE ONLY* PROMO: Purchases of 3 or more will include a random charm from my listings (excluding flag or personalized charms) ——————————————————————— COLORS: -White -Tan -Black -Gray ADHESIVE TYPE: -Regular -Ultra Stick I decided to update the design of the charm base to be rectangular because I noticed that the rectangular shape seemed to fit on more surfaces for a lot of the guns out there. Also, the rectangular design looks cool. Circular Gen 1’s and 2’s will continue to be offered as well. The Rectangular Universal Charm/Keychain Base allows you to attach any Keychain you own to your gun. Finally, all those souvenir keychains you bought while on vacation can serve a purpose. The base was designed to be small enough to fit almost anywhere on the gun without getting in the way, but also to allow enough space on the loop for any ring you want to attach. The adhesive backing allows for you to place the base on any flat, non- moving surface of the gun so that you can customize it to your liking. To attach it to the gun, simply remove the layer form the backing and stick it the gun. Keep pressure on it for about 15 seconds and you'll be good to go. What’s is Ultra-Stick? Ultra Stick is a much stronger adhesive backing for the charm base. This is for you “high speed” folks that do a lot of quick movements with your gun and you want that assurance that it won’t fall off. However, with Ultra Stick, it will also be more difficult to remove afterwards to put in a different place or on a different gun, so make sure you put it where you will want it. It isn’t impossible to remove, it just isn’t meant to be placed and removed over and over again. Comes with base and ring (souvenir keychain shown in pictures not included)
