2 4” Blue Tinted Glass Tumblers Heavy Bottomed Catch Light Beautifully

Pretty blue tinted glass tumblers. These beauties catch the light and practically glow! They hold about 8 ounces. One has a little circle stain in the bottom. I see no chips or cracks. Google tries to tell me they are Mikasa Crystal, however, these are tinted blue. What I do know is they're definitely lovely. Please see photos for details.
