Vintage Fountain Pen Ink Sac Sack Diaphragm Cement Sealant Adhesive Shellac
Description
Up for sale is one small bottle of ink sac and Vacumatic diaphragm cement. It is 100% Amber colored pure Shellac. It is great for cementing ('sticking' not gluing, so it can be undone) vintage fountain pen ink sacs on to the section, and is also perfect for cementing Vacumatic diaphragms on to the filling unit.
Each bottle holds about 5 ml. There is a brush attached to the inside of the cap that is perfect for applying the cement - like you would find inside a bottle of nail polish.
I use the exact same Shellac and bottle/cap brush on the vintage pens I repair. I haven't kept count but I know I've done over 50 pens, and my bottle still has a some shellac in it. It goes a long way.
Oh, Shellac is a petroleum based product and falls under USPS HazMat material guidelines. eBay raised their fees on July 16th, 2026 for this type of material.
