I recently had 6 Sheaffer Balance Vac-Fills repaired by Francis.
His service, communication and advice are top of the line.

I have other Sheaffer vacs that have been restored "conventionally". This system in my
limited experience now holds approximately 20-30% more ink.
Info is here: www.penpedia.com

I will be selling these and other pens in the marketplace, soon.

I have no hesitation whatsoever in recommending Francis and his Cartridge converting system!

Thanks again Francis!

Steve
