LAMY M21 Ballpoint Refill - Pack of 4

Quality refills for ballpoint pens are more complex than one might first think. The asserted pressure and motion created when writing sets the ball on the tip of the refill rolling across the paper. On the inside of the pen, the ball is in permanent contact with the ink paste, and through the rolling movement, it takes on the paste and transmits it onto the paper. Sounds simple. However, in order to keep the ball rolling smoothly and without smearing, top quality precision craftsmanship is required.

High-end ballpoint pens from LAMY always produce an even line and never leak or blot. So they are a major contribution to attractive handwriting. In accordance with ISO 12757, LAMY ballpoint pen cartridges do not contain any toxic substances and are therefore environmentally friendly. Moreover, they are waterproof which is an important feature when it comes to the signing of contracts as well as the issuing of receipts and copies.
