Our glass flask bottles are ideal for storing alcohol, liquor, and are a creative choice for atypical applications such as BBQ sauce. We offer sizes ranging from 3 oz, 6 oz, 8 oz, up to 1 liter. Traditional flasks can be mated with a tamper-evident lid. We offer swing-top flask bottles too. Glass flasks add sophistication and a premium appeal to the contents inside. Many customers buy plastic flask bottles for their shatter-resistant and light weight properties.
