Marvy Uchida LePen Fineliner
The LePen by Marvy Uchida is a sleek fineliner with a 0.3 mm plastic nib, made in Japan. The water-based, acid-free ink dries quickly and is smudge-resistant – ideal for fine lines in planners, journals and sketches. Jade is a cool, mid-tone green with a subtle blue shimmer: calm and clear, without tipping into grass green.
Features
- 0.3 mm plastic nib: The sturdy nib delivers an even, clean line even when writing quickly – no fraying, no broadening under pressure.
- Water-based, acid-free ink: Non-toxic and dermatologically compatible. The ink is not waterproof and not archival – designed for journalling, sketches and decorative use, not for archive purposes.
- Quick-drying and smudge-resistant: On smooth paper the ink dries quickly, so lines barely smudge when you continue working.
- Sleek plastic barrel with slip cap: At 8 mm diameter and 145 mm length, the shaft sits comfortably in the hand. The cap clips firmly and reliably protects the nib.
- Colour-coded cap: Cap colour matches the ink colour – grab from a full pen box and you'll spot the shade immediately.
- Metal clip: Keeps the pen secure in notebook pockets or clipped to the edge of a planner.
Use & Tips
- Bullet journal & planner: The 0.3 mm nib suits tight grid cells, fine tables and small lettering. Jade works well as an accent colour for trackers, habit columns or calendar marks.
- Hand lettering & sketches: The nib produces an even line width with no pressure variation – no flex, just consistent, controlled lines.
- Paper choice: On smooth, calendered paper the ink flows cleanly with no bleeding. On highly absorbent paper the line may be slightly wider.
- Layering & blending: Since the ink is water-based, you can layer it with watercolour or brush pens after it dries – Jade as an underlay gives watercolours a cool undertone.
- Scrapbooking & forms: Suitable for decorative lettering and filling in planners. Don't use for legally relevant documents (contracts, certificates) due to lack of archival quality.
- Cap while writing: The slip cap can be placed on the back end of the barrel – this maintains balance and prevents the cap getting lost while you work.
For Fineliner Enthusiasts
The LePen belongs to the classic Japanese fineliners with polyester felt nib in compact form. The nib is made of plastic – more robust against lateral pressure than softer felt nibs, yet less flexible than a fibre tip. This makes the LePen particularly stable for ruler and stencil work. Jade (colour no. 102) is one of the newer colour variants in the LePen range and adds a muted jade green to the classic palette, sitting between teal and mint – more saturated than peppermint, more blue-green than pure olive green. The full range includes 30 colours: black, red, blue, green, yellow, orange, pink, lavender, brown, olive green, light green, light blue, steel blue, oriental blue, navy, magenta, dark grey, burgundy, mustard yellow, light mauve, sepia, coral pink, pastel peach, orchid, wisteria, periwinkle, teal, peppermint, jade and amethyst.
