Here is the my latest pen! This is an ebonite pen, with an acrylic window within the section and the barrel. It is a capless pen with a twist mechanism, similar to the safety pen one. Twisting the section onto the barrel allows the nib to come in and out. The nib is juicy and flexible (Wahl eversharp #2). The filling mechanism is a copy of Fountainbell's bulkfiller with a modified magnetic (neodymium magnet) mechanism to retain the filling pellet. The barrel end is decorated with an amethyst. The pen length is 12,6 mm length closed and 13,4 mm opened, the maximum diameter is 16mm. The filling capacity is 3,5ml with a regular stroke but can be extended to 4,2ml expelling the air of the pen, penpoint up and resucking ink again. Here are the pictures and the X-ray of the pen.
