"This is not your 'ordinary' ink pen. Lucky Shot USA brings you an ink pen with a unique story to tell — the .308 RETRACTABLE TWIST PEN. Your signature is your 'mark,' and now you can make it loud and proud with a genuine .308 Caliber Brass Shell, once-fired by and sourced from the US Military. The pen's ink can be easily replaced with a CR0SS style 8514-2 ballpoint pen refill, and replacement instructions are included. Please note that while our products do not contain any active powder, making them entirely safe for use. Therefore, we advise against bringing them to locations where not permitted. These pens are not recommended for use by children 12 years and younger. Additionally, because our Shell Casings and Projectiles are made from once-fired US Military rounds, they may exhibit minor blemishes or scratches that are consistent with their history."
