This pair of Mid Century 12 ounce glass tumblers is from Color Craft, part of their Shat-r-pruf line of vinyl coated glass drinkware. One of my Gene Florence glass pattern identification books attributes the manufacturer to Bartlett Collins under the pattern name Netting. Both could be correct, because Color Craft specialized in colored aluminum tumblers and kitchenware, not glass.The retro spaghetti string textured rubbery coating provides insulation for your beverage and protection in case the glass is dropped. The green and coral pink tumblers are 5-1/2 inches high and hold 12 ounces. Both are in excellent vintage condition with no damage.
