Spring for Parker style refills and pen kits

Spare ballpoint pen spring suitable for most pen kits that take a G2 Parker style pen refill, including all Beaufort Ink ballpoint pen kits, plus many, many  pen kits from Berea, PSI, Dayacom, Rizheng, Axminster and Taylors Mirfield. 

This spring may also fit commercially available ballpoint pens, including most Parker pens. If your pen takes a Parker pen refill, theres a good chance this spring will do the job, however, we cannot guarantee the fit, nor are we able to offer advice with regard to compatibility of our springs with commercially available ballpoint pens unfortunately, as they are too numerable to count.
