Purchased at Space Village. This is a very effective acupressure tool. I really think it's amazing. I wish they would research more and clarify why it works so well, just by containing 15g of Gibeon meteorite powder, which is particularly valuable among meteorites. According to the Space Village chief, meteorites emit far-infrared rays and have a powerful hot spring-like effect. The tools at Space Village seem to be getting more expensive year by year. I have several other meteorites and use them daily, so I'm selling this one as it's almost unused. I hope it reaches someone who needs it at a good price. Thank you for looking.
