Klaus Riding Helmet M - Color: Black - Design: Checkered stripes - Ventilation: Vents on the sides - Application: Riding helmet - Material: Plastic - Size: M Thank you for viewing. I purchased this used on this site, but it didn't have an inner lining, so I haven't used it myself. It seems you can purchase a genuine inner lining for around 700 yen online, but the M size is out of stock and I couldn't wait for it to be restocked, so I bought another helmet and am now selling this one. The item is being sold as shown in the photos. Would this be suitable as a spare for those who already have the same size, or for those who can wait for the inner lining to be restocked? No claims and no returns, please.
