These are high quality, very sturdy yet hollow lightweight aluminum parts. They come in a set of eight. They are needed for anyone who is trying to build an accurate replica x-wing pilot flight suit. The flares are worn around the leg of the flight suit. They are designed to be screen accurate and match the Rebel Legion's CRL requirements. They're manufactured hollow to make them even lighter weight. The full set of 8 weighs 18 oz. A hole is drilled in the side, so they can be riveted in place. 8 rivets are included; you'll need to use your own rivet tool.
