This is a SHOEI helmet from back in the day. It shows signs of use, so inner cleaning and maintenance are likely needed. The internal sponge has deteriorated, so I removed it as cleanly as possible. I was planning to buy sponge from a home center and fix it, but I never got around to it. If anyone needs it, please consider purchasing. The sponge is for the head and the surrounding areas. I think it's repairable. The shield also has many scratches, so replacement is probably necessary. No price reduction, please. Please purchase only if you understand.
