Repair Essentials: Pen Sacs and Sac Cement

Repairing your pens is half the fun — but you can’t do it without sacs. Here they are! We offer top-quality U.S.-made sacs made using the original White Rubber Company formula and produced on the original White Rubber Company machinery that turned out millions of sacs for Eversharp, Parker, Sheaffer, Waterman, and most of the other pen American pen companies from 1919 until the 1980s. Here you will find a broad selection of straight sacs to fit most pens along with a few special sacs that you need for popular pens such as Vacumatics and Skylines (like the one in the photo).

We also have sac cement. Our sac cement is a special high-quality orange shellac that we’ve chosen for its stickiness and for its long shelf life. Ordinary sac cements have about a six-month shelf life; then you have to throw them out and buy more. Ours stays good for at least five times that long. And it comes in a short fat bottle that’s less likely to tip over than others.

For convenience, all of our sacs except assortments come in packages of 5 sacs. Each assortment contains 10 sacs, 2 in each of five sizes.
