While these do look just like Harry Potter's glasses, they're also the essential gear to make an ideal anti-fashion statement. Black plastic, round frames, and clear lense glasses are extremely sturdy, lightweight and nerdy. Careful, you might just think you're Harry Potter wearing these! If you're wearing these as part of a costume, you can use them when you dress as Harry Potter, as a nerd, a young school boy, or a 50s party participant. They are made with plastic hinges. Fits most children ages 5 to 12.
