Starbucks Shot Glass. Clear Glass with Black Print and Level Marking. One Ounce. Front of the Glass shows Starbucks and Single 5 Point Star. A Black Measurement Level Circles the Top of Glass. Back of Glass shows 1 Oz at Measurement Level. Actual Shot Glass is About 2 1/4 Inches Tall and About 2 Inches in Diameter at Rim. I Find no Markings on the Bottom of the Glass. No Chips or Cracks with All Color Strong and True.
