The Koziol Club No. 15 Superglas is a faceted cocktail and gin glass designed for environments where traditional glassware is prohibited. Crafted from an unbreakable high-tech plastic, these transparent glasses offer a safe alternative without sacrificing style, as they are impact-resistant and fully recyclable. Each glass has a capacity of 400 ml, standing 19.2 cm tall with a diameter of 11.1 cm. Beyond their durability, these glasses provide thermal efficiency by insulating liquids four times better than conventional glass, helping your drinks maintain their temperature longer. They are food-safe and dishwasher safe up to 70°C, though a first wash above 80°C is recommended. To keep the material clear, using pH-neutral cleaning supplies and a specialized rinse aid for plastics is advised. This set comes with two pieces, making it a practical choice for those who need reliable, high-performance drinkware for poolside use or professional hospitality settings.
