Set of 2 Vintage Mouth Blown Cobalt Blue Pilsner Beer Champagne Glasses Flutes

Set of 2 vintage mouth blown cobalt blue pilsner beer or champagne flutes made by Hachar Industries of Laredo, Texas. They measure approximately 9" tall and hold 12 oz. They are in excellent condition. There is a small air bubble (see picture) which I assume is a manufacturing error.
