This Cartridge Bullet Click Pen kit replicates a 30.06 rifle cartridge. This is an extremely easy kit to make using a single tube. This kit uses a Parker™ style ball point refill or gel refill and we have made this kit using a new clicker technology. The new clicker gives a "softer click" that is also very positive and virtually trouble-free. This kit also comes with the premium rifle clip. This kit will make an excellent gift for a hunting or shooting enthusiast. Available in 24k Upgrade gold plating and in Chrome plating.
