SWANS helmet, size S (48-54cm). - Brand: SWANS - Size: S (48 - 54cm) - Color: Gray - Features: With ventilation holes Thank you for viewing. I used it once, but it didn't fit, so I'm selling it. *There is a scratch of about 1cm on the back of the helmet (see photo 5), but other than that, it is in relatively good condition. Don't miss this opportunity! m(_ _)m
