Non-LED 101 Self Inking Pens
Marco Lensmeter Ink Cartridges are replacement self-inking marking pens for the Marco 101 Lensometer and Nidek lensmeters. MA-4011 replacement lens marking pens are supplied in sets of 3 and include replacement retaining C-Rings.
Please Note: These are replacement parts for newer lensmeters only, which already employ the same pen design. Conversion from older design white plastic pins to these pens requires a conversion kit and re-calibration.
