GIFT BOX CONTENTS: ONE pen, ONE carabiner-style keyring accessory, TWO standard “D1″ ink refill cartridges (German-made Schmidt S 635 ballpoint with blue ink) and ONE spare o-ring set (consisting of one small and one large o-ring) packed inside ONE reusable and environmentally-friendly corrugated gift box. We also toss in a 100% satisfaction guarantee: if for any reason you’re not satisfied with this product, you can return it for a full refund.
A PEN THAT STAYS TOGETHER ON YOUR KEY-CHAIN: Created specifically to be used as a key-ring accessory, the sleek pen design completely eliminates any risk of getting caught and ripping apart the seams in your pocket. Our pen utilises a piston-inspired and patent-pending cap design that creates a two-stage fastening mechanism, combining the best of both a push-on and screw-on cap to ensure that the pen will always stay as one piece in your pocket.
COMPACT FOR EDC AND EXTENDABLE FOR WRITING: Measuring at a closed length of 3.3″ (8.4cm), this is one of the smallest full-sized pens you will find on the market. Completely extended with the cap posted to the back of the barrel, the pen provides a full length of 4.9″ (12.4cm) with a standard-sized 0.31” (0.8cm) diameter grip for comfortable writing. All this within a tiny package weighing in at 1.05 oz (31g)!
A FUNCTION-DRIVEN PEN MANUFACTURED TO WEATHER EVERYDAY USE: The cap and barrel housing are precision machined from solid blocks of commercial grade 5 titanium, an aircraft-grade alloy with comparable strength to steel at nearly half the weight. The pen components are held together using only friction by fitting each threaded component with o-rings rated with an unlimited shelf life. The pen even comes with its own screwdriver for replacing its ink refill, hidden in plain sight!
DESIGNED TO FIT ONE OF THE SMALLEST REFILL STANDARDS ON THE MARKET: The screw fitting that goes inside the pen barrel is machined out of phosphor bronze, and it acts as an ink refill retainer designed to hold a standard-sized “D1″ multipen ink refill. D1 refills are usually manufactured with ballpoint writing tips, and at a standard length of approximately 2.6” (67 mm), it is small enough that you can easily wrap up a few spares to carry around with you in your purse, bag, or wallet.
