"Ah, the Hand of Glory! Insert a candle and it gives light only to the holder! Best friend of thieves and plunderers! Your son has fine taste, sir."
-- Mr. Borgin, when Draco admires the object in Borgin's shop
The Hand of Glory is a magical object which gives light only to the holder. It looks like a shriveled arm.
Draco Malfoy asked Lucius Malfoy to buy him one at Borgin and Burkes just before his second year (CS4). Evidently he got it (HBP6)
The Hand of Glory is drawn from English folklore, described as a withered human hand whose fingers, when lit like candles, cast a charmed sleep on members of the household so the thief can rob the house.
