These are arm rings used at Itoman Swimming School. Both were labeled, so I've covered the names with a marker, which is why I've listed them as "used with scratches and stains." Aside from the marker, there's a large orange line, possibly from being stored stacked. I used an electric air pump to inflate them, so I didn't use my mouth. I inflated them before listing, and they seemed fine, but they haven't been used and have been stored at home. Please refrain from purchasing if you are concerned. They will be folded small and shipped via regular mail.
