Sailor Lecoule Fountain Pen clear (MF)

The Sailor Lecoule clear is a completely transparent fountain pen made from PMMA resin – a material that gives the barrel a crystal-clear, slightly cool appearance whilst allowing you to see the ink and ink flow. The stainless steel nib in MF (Medium-Fine) size writes with a precise, fine line and pleasant tactile feedback on paper. The cap is secured with a screw thread – reliable and won't open accidentally in your pocket.

Features

• Completely transparent barrel made from PMMA resin: Barrel, cap and grip section are all crystal clear – filled ink is visible from outside, which is particularly striking with vibrant or shimmer inks. You can always check the ink level without opening the pen.
• Stainless steel nib MF (Medium-Fine): Sailor's MF nib is equivalent to an Extra-Fine in Western sizing and delivers a sharp, controlled line with light tactile feedback. Precise and well-suited for detailed writing.
• Screw cap: The closure sits securely and reliably seals the pen – no risk of the nib drying out during longer breaks between writing sessions.
• Cartridge and converter compatible: Works with Sailor ink cartridges and standard Sailor converters. With a converter, you can use the entire Sailor ink range – and the transparent barrel makes the ink colour inside visible.
• Lightweight and compact: At 12.4 g and 123 mm length (closed), it's a handy pen that feels well-balanced in the hand even with the cap posted (141 mm).
• Postable – cap can be posted: The cap can be slipped onto the back end, extending the writing length to 141 mm and pleasantly balancing the weight distribution for extended writing sessions.

Use & Tips

• Show off your ink choice: The transparent barrel is ideal for trying out different ink colours – whether deep indigo, vibrant turquoise or soft sepia. The colour is immediately visible through the walls and changes the character of the pen with each new fill.
• Everyday writing and journalling: The MF nib produces a fine, sharp line that looks particularly crisp on smooth, fountain pen-friendly paper. Well-suited for dense notes, bullet journalling or daily entries.
• Cleaning and changing ink colours: Because the barrel is clear, you can directly observe the cleaning progress – when the water is truly running clear. Practical when switching colours frequently.
• Introduction to Japanese nibs: If you're trying a Japanese nib for the first time, the Lecoule's MF nib is a good starting point: controlled line width, consistent ink flow, little room for error due to nib positioning.
• Storage and transport: The secure screw cap makes the Lecoule a reliable everyday option for shirt or jacket pocket – with no risk of ink stains from a loose slip cap.

For Ink Enthusiasts

The completely transparent PMMA construction makes the Lecoule clear the ideal demonstrator pen in the affordable segment: ink visibly flows from the converter through the feed to the nib. Sailor's MF nib writes on the Japanese scale – this means a line width equivalent to Western Extra-Fine nibs, with characteristically crisp line definition and minimal ink lay-down. This limits show-through and feathering on most fountain pen-friendly papers and makes the nib particularly interesting for multi-colour notebooks or journal pages where both sides will be used. Compatible exclusively with Sailor cartridges and Sailor converters.
