This set of 6 authentic horseshoe nail wine glass charms will certainly be the topic of conversation at any party. Each nail is hand bent by me on my New Hampshire horse farm. Each nail has a different rattail cord on it so each person can identify their own wine glass. Not recommend to keep on glass during washing. This steel will develop a lovely patina over time and may rust if contacted with water. Patina and rust can be removed with a little steel wool to re-shine it. Ships in a 3.5 inch by 3.5inch gift box. This makes a great hostess gift!!!
