This fun and functional set makes it easy for everyone to keep track of their drink at springtime soirées—and can also be used to mark buffet dishes, plates and more. Simply write directly on glass, glazed ceramic or plastic and wait one to three minutes for the ink to dry. Certified non-toxic ink washes off easily with warm, soapy water but won’t smudge during use. For chilled wines, write your name of the base of the glass.
