Model 008 (Clear Gold-Plated): Gold-plated quill clip, with transparent pen barrel, the visual effect is more harmonious when filled with blue/black ink, focusing on light luxury texture.

Tips for use and care

Ink selection: Prioritize the use of non-carbon ink to avoid carbon ink clogging the transparent pen barrel and piston structure; color ink players can choose dye inks with good fluidity to better show off the appearance of the transparent pen barrel.

Piston maintenance: Rinse the piston with clean water before first use to avoid factory residual grease affecting inking; when not in use for a long time, empty the ink, rinse the piston with clean water and dry it to prevent the ink from drying out and damaging the seals.

Writing Adaptation: EF/F tip is suitable for ordinary paper/notebook above 80g, M/Artist tip is recommended for paper above 90g to reduce ink bleeding.
