Tumblers are 3-1/2" tall and 3" across the top. The rim seems to have a small lip indicating that the original use required a snap on lid. We don't have documentation that MacBeth-Evans made the tumblers, but we now know that they are part of a Salton yoghurt-making set.
Member TallCakes reports: "I do have the Salton yogurt-maker and milk glass containers that was purchased in mid 1970s. The size mentioned and the details shown in the gallery do match the Salton containers. I'm fairly certain that the gallery piece is indeed a Salton yogurt-maker container....The 'lip' of the container is designed to help retain the plastic lid. These are a bit small for a tumbler and only hold 7 oz. to the brim.
