60's Fizz-Whiz Bottle Caps - 2 - Metal Bottle Caps - 60's Barware Tools

This is a pair of 60's Fizz-Whiz bottle caps. Made in the USA of metal (aluminum/tin?) and rubber, these bottle caps are supposed to keep open bottles sealed. Each measures approximately 1" tall and 1 5/8" across. The silver one has "Cheers with Acadian" on the side. PLEASE NOTE: these DO NOT work for the majority of today's glass bottles. The bottles that can be used must not have "rings" around their neck. The necks must be smooth. In very good vintage shape, there is some scratching to the metal. See the pictures for details.
