Works so well that I give packages as gifts to people I care for. Does not smear easy to use (I have RA) and the ink is great. There are choices as to the size of the print.
Originally I had the tru red gel pen with removable cover but the cover was a bit of a hassle to tale off and put on everytime i needed to write something down. When i heard there was a retractable version I was anxious to get my hands on one or a few because they don’t smudge when i write with them which I know is a big issue for us left-handed individuals.
