The Power Gauntlet used to house the Infinity Stones in Avengers: Endgame is pretty sweet, and you could own a replica.
If you’re a super fan, you can pre-order the Marvel Legends Series Power Gauntlet on Amazon for $100. It’s almost like a movie prop; the gauntlet has incredible detail, articulating fingers, the Infinity Stones light up, and more. The Power Gauntlet releases on August 19th, but pre-ordered purchases will ship out on August 15th.
Demand for the gauntlet is pretty high, so the supply may run dry sometime soon.
