Purchased new from Ippin Kan one month ago. This is a set of 3 insulators from Ippin Kan's original AIRBOW series. The third photo shows the most significant scratch. It looks quite bad in the photo, but in reality, it's not that noticeable. It feels more like a color unevenness than a scratch when you touch it with your nail, so please don't worry. These are spike bases, so there is a small hole in the center to be used as a receiver for spike insulators. They cost 5830 yen at Ippin Kan. Thank you.
