Only 18, individually numbered pens, have been produced. Crafted from glorious marbled ebonite and featuring an 18k single-tone nib. The pen features a piston filling mechanism, accessed by unscrewing the blind cap.

The Astrum features myriad of blue and orange tones – being crafted from ebonite, the pen has an extremely tactile and warm finish, which lends it to long writing sessions.

The pen comes housed in a luxury presentation box, which includes a bottle of ink.
