Ahhh, a gift fit for a Scorpion King. Present these Scorpion Knuckles to Mathayus, and you should get a hearty Dilly, dilly! in return.
Unless he likes Bud Light too, in which case, enjoy your tour of the Pit of Misery.
Alternatively, stay home from the realms of prehistoric worlds, and keep the Scorpion Knuckles for yourself. They'll look great in any cosplay or fantasy weapons collections, right alongside the Skull Knuckle Knife and Scorpion Blade Arm Gauntlet.Another idea: Scorpion Knuckles paperweight.
