Anterique Ballpoint Pen End Cap Dark Blue

The Anterique BP1 rear section in dark blue with gold accents is the back housing component of the modular BP1 ballpoint system. It houses the push mechanism, gives the pen its characteristic 1960s silhouette, and can be combined with a matching grip section (front part) – the refill is contained exclusively in the front part. The matte dark blue of the plastic housing has a calm, timeless quality, whilst the gold clip provides a clear, warm contrast.

Features

• Modular System: The rear section functions as a standalone component of the BP1 system – front and rear parts can be freely combined in different colours to create individual colour pairings.
• Push Mechanism: The push-button mechanism sits in the rear section and enables quick, one-handed opening and closing – practical at the desk or on the move.
• Gold Plastic Clip: The contrasting gold clip secures the pen safely in shirt pockets or notebook covers and creates the characteristic retro look of the Anterique line.
• Lightweight Plastic Housing: The ABS plastic is robust yet light enough that even longer writing sessions are possible without fatigue – the grip remains relaxed.
• Dark Blue and Gold Finish: A deep, darkened blue with a matte surface – no reflections, no gloss, but a dense, velvety colour that pairs beautifully with warm ink tones such as sepia, bronze brown or bottle green.

Use & Tips

• Create Colour Combinations: Dark blue/gold as the rear section can be combined with a transparent or burgundy grip section – the result is a pen that embodies two characters in one.
• Refill Contained Only in Front Part: If you purchase the rear section alone, you'll need a matching BP1 grip section (front part) with included refill to assemble a complete pen.
• Low-Viscosity Oil-Based Ink: The Anterique refill contained in the grip section writes with "Mach Ball" oil-based ink – very fluid for a ballpoint pen, with a fine 0.5 mm tip for precise lines. The ink is smudge-resistant and not archival.
• Use in Planners: The 0.5 mm line width and consistent ink flow make the fully assembled BP1 a pleasant companion in diary layouts with tight line spacing and small boxes.
• Refillable: The BP1 refill is available separately – the housing is designed for long-term use.

For Ballpoint Enthusiasts

The Anterique BP1 draws formally on American ballpoint pens from the early 1960s – rounded proportions, compact construction, continuous polished or matte body without a sight window. Anterique's own Mach Ball ink operates with ultra-low viscosity: the ink reservoir is oil-based, the rollerball tip is precision-manufactured, and a built-in spring in the writing head actively regulates ink flow – this prevents the blotting that can occur with conventional ballpoint refills when writing quickly. For pen collectors who deliberately combine housing parts, the modular system opens up an additional design dimension beyond complete pens.
