I find this nerd glasses simply Klasse.Die delivery was very quick (and Mo.bestellt Mi.war they hier..allgemein things that I order from Amazon until now all arrived within a few days) the packaging looked only not so sure , but my glasses are intact angekommen.Ich have something not so stable expected, but it is really good verarbeitet.Die glasses are really Klarglas.und at the price really can not complain now;) I'd always order you again.! :)
