The Ti Click from BIGiDESIGN (aka BigiDesign) is a retractable pen machined from grade 5 titanium. Titanium has become a very popular choice for EDC pen bodies because of its high strength and low weight. The Ti Click’s major claim to fame is that it’s compatible with over 100 different refill types. No modifications required.
Ti Arto EDC is a titanium pen that is sold in Midnight Black, Stonewashed, and Machined Raw finishes. It has a handy everyday carry-inspired design can work with hundreds of different pen refills. This is possible because the tip of the pen is actually a clamp that grabs the front of the refill and the back of the pen can move up or down to accommodate all sizes of refills.
