? Matching titanium pair: ArkPro Ultra Titanium and O¡¯Pen 3 Titanium ? Pure titanium bodies with finely etched, three-dimensional tactile details, polished surfaces, and a nano-protective coating ? Limited to 2,222 sets, with a dedicated case for everyday storage The third chapter of the C.O.R.E. Series introduces the Titanium Duo. Your voice. A new chapter in titanium. Inspired by the community¡¯s call for titanium, the Titanium Duo brings together the ArkPro Ultra Titanium and O¡¯Pen 3 in a coordinated EDC set. For this chapter, we sought a special material to reflect the craftsmanship, originality, and rarity of the C.O.R.E. Series. Titanium became that choice. Both pieces feature TA2 commercially pure titanium bodies. Finely etched, three-dimensional tactile details combine with polished surfaces and a nano-protective coating to highlight the texture of the metal. The shared material and finish give the pair a consistent character. The ArkPro Ultra Titanium retains the versatile functionality of the ArkPro Ultra, while the O¡¯Pen 3 completes the everyday carry pairing with a meteor-shower-inspired grip, smooth writing, and 120-lumen illumination. Limited to 2,222 sets, each Titanium Duo features matching serial numbers on the ArkPro Ultra Titanium and O¡¯Pen 3 Ti, numbered from 0001 to 2222. The edition also offers a subtle nod to titanium¡¯s atomic number, 22, connecting the material to the story behind the C.O.R.E. Series.
