An IDSA member has come up with a glass fountain pen that can write with anything from wine to soy sauce.
Jessica Chan, IDSA, says WINKpens also can be filled with juice, tea , dark beer—just about any fluid that contains a staining property. The standard model is made of a two-sided, glass writing nib; a coupler; transparent glass housing; a twisting, refill ink system; and a barrel cap. Chan, of Portland, OR, hopes to sell her WINKpens in wineries, travel companies, art supply stores, specialty gift shops and online.
