According to the manufacturer, the S.F. 15 staples are no longer manufactured and they recommend using the S.F. 4 staples as the best replacement. However, the manufacturer did mention you may experience some jamming with these staples and they may not work as smoothly as the S.F. 15's, but they are the best replacement for the discontinued S.F. 15's.
