Following the crowdfunded success of its well-designed Type-A & Type-B pens, Brooklyn-based CW&T Studio created Type-C, a titanium bookmark pen with a detachable clip. Precision machined of lightweight titanium, it features a book-friendly flat design and a sprung steel arm that protects the pen-tip when not in use. Flip it around to snap into writing position; it uses Pilot Hi-Tec-C Coleto ink cartridges which come in 15 colors and multiple thicknesses. Another funded Kickstarter.
