If I killed dead a being of pure hatred and encapsulated it in its lantern, I'd take the rupees from the Poe Collector for it rather than let it dangle from my neck so dangerously close to my heart. Sure Poe Souls can restore health, but they can damage it too. I'm already damaged enough. However, Hylians still in peak form, or those who like tempting fate by wearing dangerous necklaces, will probably dig GeekOUTlet's Legend of Zelda Poe Soul in a Bottle pendant.

Each 1-1/4" bottle houses a red, blue, green, yellow, or purple glow-in-the-dark Poe Soul with searing yellow eyes guaranteed to terrorize children. Particularly those who don't give everyone a turn at Skyward Sword on the Wii. Ahem, my nephew Kyle. Poes are all hand-painted, so precise manifestations of evil in their expressions may vary. Pendants arrive on an 18" ball chain, and also include a mini UV keylight for recharging the spirit back to his toxic-looking glow.
