Fountain Pen Sac Pure Talc (Talcum Powder)
3-gram container of pure powdered talc for use on Pen Sacs & Restoration Supplies and diaphragms. No oils or fragrances to rot the latex. Prevents sacs from sticking to the pressure bar and barrel wall. Also aids in rolling back Vacumatic diaphragms onto themselves. This container will coat scores of sacs. We recommend applying the talc with a 1∕4" make-up or soft artist's brush. The sac should be dusted with a film of talc, not thickly caked.
