This is a Lot of 12 Shat-R-Pruf Color Craft Mid-Century Spaghetti String Swirl Tall Tumblers Drinking Glasses 4 - 15 oz. and 8 - 12 oz.!

Color Craft spaghetti string glasses are an iconic glassware from the 1960's.

Shat-R-Pruf pieces were made of glass and coated with plastisol, a liquid form of vinyl cured by heat to set the shape. If you look closely at the rim you can see the glass is clear. The actual color is in the Tu-tone Plastisol, the first layer being the solid coating and color, the second layer being the spaghetti string design.

Plastisol feels rubbery to the touch and makes the glasses easier to hold. The vinyl coating also makes the glasses shatter proof and acts as an insulator. This means drinks stay colder for longer, but with less slippery condensation on the glass!
