No dilution of your beverage with ice or refrigerating them for long hours to maintain the temperature – The Self-Chilling Cocktail Glasses can do so with a simple reusable insert. You simply need to freeze the reusable insert and place it at the bottom of the glass which then gets magnetically sealed in place. That way, you can chill your beverage at the right temperature without diluting them with ice unnecessarily. For a pre-chilled drink, the insert can help in maintaining the temperature for a longer span of time. Every glass is hand blown and looks pretty neat as a design. Time to enjoy your cocktails at that perfect temperature which brings in the ideal taste and quality.
