This is a one-of-a-kind replica aviation flight pilot helmet, a custom HGU-33/P, decaled and painted for the No. 1 F/L flight leader of the Japan Air Self-Defense Force's aerobatic team, the Blue Impulse (new bayonets/new black mask included). [Mercari Product Description] Perfect for display or cosplay. Size is free size, approximately M to XL. Even I, who wears XXL (62-63cm) for motorcycle helmets, could put it on by spreading it sideways. The helmet shell is small, but the inside is spacious. Includes aviation-specific bayonets (metal fittings)/bayonet receivers, and a new black mask that resembles an oxygen mask. If you remove one bayonet and let the mask hang, you'll feel like Tom Cruise. It has a green smoke and clear visor, both of which can be used separately, and the chin strap is a slide ratchet type for motorcycles, allowing for one-touch attachment and detachment. *The slide lock in the center of the visor is a dummy. Do not turn the screws. Light blue metallic paint, outdoor-resistant decals, two-part urethane clear coat, and compound finish. The original helmet is a new/unused item, but due to long-term storage, it has been disassembled, disinfected, and washed, and then reassembled with fabric softener for this listing. The deteriorated edge rubber has been replaced with new ones. Please be aware that those sensitive to smells may notice a slight material odor due to the long-term storage of the original item. There are no visible scratches on the visor, etc., but there are inevitably variations in manufacturing quality and minor scratches from storage. Please be sure to check the condition of each part in detail in the photos. This is a used item, a hobby creation made with custom paint. Sold as-is, with the images taking precedence. No returns, no claims, and no refunds. [Please Note] Please use this for display or cosplay purposes.
