G Pen Hyer Quartz Tank Cap
Hyer Quartz Tank Cap is a replacement top for the quartz tank on your G Pen Hyer. It lets you replace a lost or worn cap without buying a whole new tank.

A fountain pen without its cap
Eustace writes letters by hand every Sunday, always with his old fountain pen. Also, it was a gift from his first boss, and it has signed every lease he has ever had. Last month, though, the cap rolled off the desk and vanished for good.
Without a cap, the nib dried out by morning. As a result, his letters came out scratchy and pale. So he tracked down a matching cap at a tiny shop across town. Now the ink flows smoothly again, and Sunday feels like Sunday. In short, a cap may look small, yet it keeps the whole tool ready to go.
