Anybody remember Ko-Rec-Type?

Anybody remember Ko-Rec-Type? I found this one sad little strip of it tucked into some old papers. I went through this stuff like mad in high school, but when I went off to college I was given the greatest of gifts: a Smith-Corona Coronamatic typewriter with a correction button -- it had two cartridges, one for ribbon, one for correction tape, and with the press of a button you could correct the last character automatically. Anything more than a one-letter mistake was still a tedious process. I still wish my word processor would ding as I approach the end of a line, just for old time's sake.
