Super safe, super strong, super toughened - the Perfect Pint is designed for optimum strength and breakage so that when it does finally shatter it will break into roughly twice as many pieces as standard fully toughened glassware, fragments so small it is impossible to cause serious lacerations. The Perfect Pint is available lined and CE stamped and also with nucleation. Nucleation involves the etching of the bottom of the glass and is designed to increase the effervescence of the product and maintain the head of the drink, as well as improving the appearance of beverages when served.
