These pieces are a great conversational piece! They are stave pieces cut on a specific angle to balance a wine bottle with no help just center of gravity of a full wine bottle! Yes, we said full wine bottle! If the bottle is not full, we cannot guarantee the bottle will balance. So, if you open the bottle, you mind as well finish it seeing that you can no longer balance it again! The balancers themselves are made from barrel staves. The staves are cut, stained in a dark walnut color and then have a polyurethane finish. The single balance one bottle, double balance one or two and the triple balance one two or three bottles!
