Fountain Pen Sacs

Replacement sacs (bladders) for restoring vintage fountain pens. Our latex rubber sacs are made using the same latex formula and on the same equipment used by the White Rubber Company, which supplied most of the major pen manufacturers with sacs from 1919 to 1985.

For information on sac sizes and what pens they fit, please refer to our Sac Size Guide.

Sacs are sold each and by size.
