...the one on the left has longer than usual SDPs...also has something going on in the glass on the lower wire ridge...no damage...something must have happened while in the mould or from cooling...but there is no damage just a little glass malformation ...the other piece has either rounded SDPs or sharp RDPs...you decide......this one is is a very strong hemi-blue color....only damage on this piece is a scuff mark in the wire groove...take the pair for $25 shipped....
