Wand, dubbed 'Evil Stick', promises 'wonderful music', magic and fairies
But underneath silver foil, it shows image of girl slitting wrists with knife
Available from dollar store, it also emits cackling laugh and flashing lights
'I'm outraged,' said Nicole Allen, who purchased toy for her daughter, two
Store's owner said it was parents' responsibility to read the wand's label
He added that he believed the product was appropriate for older children
'For a five, six, seven, 10-year-old, I mean they see that on TV everyday'
