Summer Season 2025 These are the incredibly popular, heat-resistant double-wall glasses that sold out immediately after release. They look beautiful with any drink, hot or iced, and are simply captivating. I love Starbucks double-wall glasses and buy them every season, collecting them. The item for sale here is a new, unused one that I bought as a spare, and it comes in its original box. These are recommended for anyone who doesn't yet own a Starbucks double-wall glass, or for those who are already collectors. I will pack them in cardboard to prevent breakage during shipping.
