I want to plan a wine tasting party around these. Just imagine adding them to the table as the night progresses and as the bottles empty. I really think everyone would get into making them as well. Some bottles could even have more than one arm. I'm not sure what the holders are, but I know I could spend some time at home depot and find something. Clean, simple, and functional never fails.
Or just buy them here and bring them to the next party.
