Designed by custom knife maker Darriel Caston, the Rocket Pen is nothing like your classic Bic disposable. The oval design offers flatter sides and makes the Rocket Pen feel elegant and comfortable in the hand. Outfitted with a bayonet mechanism with a lateral slider, the pen is both addictive and functional, making it fun to play with between note-taking sessions. Made from anodized black aluminum or brass, depending on the model you choose, the pen is also incredibly durable and attractive. The Rocket Pen takes Fisher Space Pen Refill #PR4 and Parker-style refills. If you want a writing instrument that’s sleek, refined, and built to last, you just found it.
