Not only does Stark Contrasts make 3D-printed Sword Earrings, Stark Contrasts makes 3D-printed She-Ra: Princess of Power Sword Earrings! Holy Etheria, Swift Wind, I thought I'd hit the jackpot with Astrosex, but Sword of Power earrings? I just found the best gift ever for my wife.
Even if your wife doesn't also happen to be named She-Ra: Princess of Power like mine, she might like her some mighty She-Ra Sword earrings. Or perhaps she'd prefer to impale her lobes with a Zelda Master Sword. Or a fencing sabre. Or Arya Stark's Needle. Perhaps you would too.
Sword Earrings take their stab at becoming jewelry via stainless steel earring posts hidden in the center of the blades. The blades then slide off / re-sheath when you want to wear them.
