Hood River's Craig Graffius' hand-blown glass wine stoppers are one-of-a-kind. They are made with a blend of Pyrex and borosilicate glass to ensure durability. The rubber stopper is laboratory tested for resilience and pliability. The stoppers fit all standard size wine bottles and come in many different marble-like colors. We offer two different sized tops: the smaller round top or the large flat top shown here. Because each piece is a work of art, the colors will vary. If you prefer a dominant color, please specify which you would like in the gift message box when you check out.
