Xcoser Avengers Endgame Quantum Helmet

Xcoser Avengers Quantum Helmet Endgame. Helmet is used / pre-owned in relatively good condition with some wear. Most noticeable is the crack in the face shield (see pictures). Some other scuffing throughout. Inside has padding to make it comfortable to wear. The resin material does not have any give. No size of the helmet is indicated. I wear size 7 1/2 fitted hat and this does not fit on my head.
