These heavy base Tumblers are 11oz and made in the USA. Graphic "Perfect Pour" lines in white & black denote 2oz & 5oz pours. All inks are durable and dishwater safe—BUT for best results, a light hand-washing helps preserve the color print. Choose from four designs, (although how great of a gift would a set of four be!): Boys Night/Bar Fight, Small Batch/Big Headache, Man Cave/Man Down or Neat/Sloppy.
