This is a posable action figure from the Nendoroid series.
Adapted from Good Smile Company's website:
From "Avengers: Endgame" comes a rerelease of the DX Nendoroid of Captain America! The unique chest and shoulder patterns of his Endgame suit have been carefully remade.
He comes with both a default face plate and an interchangeable courageous face plate for various displays. As for his optional parts, Captain America's famous shield is included. Head, hair and mask parts are included allowing you to display him either masked or unmasked.
The DX version also includes another Nendoroid body wearing his past self's costume. Additionally, another version of his shield after it was broken by Thanos, Mjolnir and a special stand base based on the final battle from the film are included, allowing you to recreate the famous "Avengers Assemble" scene from the film. Be sure to add him to your collection!
