Check the listing for details. Universal Charm/Keychain Base Gen 1. Condition: New. Listed at 5.99 USD. *FOR AIRSOFT USE ONLY* I now have a new and improved Gen 2 version available for purchase PROMO: Purchases of 3 or more will include a random charm from my listings (excluding flag or personalized charms) ——————————————————————— The 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 be to placed and removed over and over again. Comes with base and ring (boot keychain shown in pictures not included)
