LAMY M21 Ballpoint Pen Refill 0.7mm

LAMY M21 Ballpoint Pen Refill 0.7mm

A multi pen only earns its place on your desk when every color writes the moment you click it. The LAMY M21 is the compact ballpoint refill at the heart of LAMY's three-function pens and the LAMY 2000 four-color pen, and this pack keeps those mechanisms loaded and ready. Each refill carries the printed LAMY M21 barrel marking with the ISO 12757-2 DM size code, a polished metal writing tip, and a 0.7mm ball that lays down a calm, even medium line.

Because the M21 comes in four working colors, one slim pen body can cover a full day of notation: black for the page, blue for sign-offs, red for corrections, and green for margin markup. Choose single-color 5-piece packs to top up the shade you burn through fastest, or keep the whole team writing with the 20-piece transparent storage box in black.

Frequently Asked Questions

Q: Which pens is the LAMY M21 refill compatible with?
A: The M21 is designed for LAMY's compact multi pens: the 745, 746, and 759 three-function models, and the LAMY 2000 four-color ballpoint pen.

Q: What line width does the 0.7mm tip produce?
A: The 0.7mm medium ball writes a clear, even line that stays legible in small handwriting while remaining bold enough for headings, corrections, and color-coded notes.

Q: What colors and pack sizes are available?
A: You can pick 5-piece packs in blue, black, red, or green, and black is also offered in a 20-piece transparent storage box for heavier use.

Q: Is the M21 a gel or rollerball refill?
A: No. The M21 is a ballpoint refill, so it writes with the quick-drying, low-smudge character typical of ballpoint ink rather than the wetter laydown of gel or rollerball refills.

Q: How do I swap the refill in my multi pen?
A: Unscrew the pen body, slide the spent M21 straight out, and press the new refill in until it seats firmly. Reassemble the pen and click through each color once to confirm smooth, full extension.
