This is one of those products that is just crazy enough that it has to be mentioned. It happens to be a comically oversized Mjölnir, specifically a foam prop based on the Marvel Cinematic Universe depiction of Thor’s legendary hammer. Weighing in at 20 lbs., featuring dimensions of 25.4″ x 16.8″ x 47.8″, this prop is fairly hefty for a foam piece, with a hefty price to match: $249.99.
