i ordered 3 of these harry potter glasses to go along with The Looking Book i had recently purchased for grandchildren.  We read the book and then i presented them with the glasses.. "lookers" ... and we had the best fun .  one of our twin 4 year old grandsons .. asked if he could take his home to show his dad ...the other asked grandma can we keep our lookers forever??  the 9 year old granddaughter actually resembled a harry potter character and quite enjoyed that part ... i was almost surprised at how much she enjoyed the story and glasses ... we used the "lookers" in the backyard, on a neighborhood walk ... and just had fun all day til they wore them home.  The Looking Book and these glasses are a great combo.  good product, service, price.
