I thought I was going over the top purchasing these for my 5 yr old's police costume (I got him a donut too, evil grin).  My son LOVED the glasses.  My only concern is durability; however, these will do . . . I did buy them for a 5 yr old after all . . . there aren't glasses made that are durable for a 5 yr old.  He has a tour at a police station coming up . . . he cannot wait to wear them on the tour!
