***Note*** : 
 
Some minor surface blemishes are normal and are not a sign of defect or mishandling.  The QPQ surface finishing is an industrial process and products are placed together in baskets and dipped in multiple chemical baths.  Slight contact and abrasion from the contents in the baskets are unavoidable.
