The Pilot Custom 823 Amber Fountain Pen is the warmest expression of the Custom 823 family, its rich amber resin casting the pen in the colour of aged honey or well-worn tortoiseshell. Where the transparent versions invite you to watch the ink, the amber barrel gives the pen a more classical, collected quality — less laboratory, more writing room. The same vacuum filling system is at work beneath the surface, its generous capacity one of the Custom 823's most compelling practical virtues. The 14k gold nib writes with that characteristically Japanese smoothness — responsive and slightly springy, with just enough feedback to make long writing sessions genuinely pleasurable. The screw cap closes securely and the pen posts well for those who prefer a longer, more balanced feel in hand.
