Bring a refined, reusable option to everyday beverage service with this double-wall glass tumbler collection. Available in 8-ounce and 14-ounce sizes, the sets are designed for coffee, tea, lattes, espresso drinks, and iced beverages. Each 2-pack includes hand-blown borosilicate glass tumblers with clear glass sip lids, silicone seals, silicone sleeves, and silicone bases. The double-wall construction creates an insulated design while the transparent glass provides a clean, modern appearance that lets the beverage remain visible. The glass sip lid includes a drinking opening and can accommodate a straw, while the silicone seal provides a secure-fitting lid design for convenient everyday use. Removable silicone sleeves offer a comfortable-feeling grip, and the silicone bases add stability when placed on a countertop, desk, or table. The reusable construction makes these tumblers suitable for home, office, kitchen, and travel routines. Color options include Cyan, Niagara, and Black, depending on the selected variant. The provided specifications state that the tumblers are microwave- and freezer-safe. For care, hand washing is recommended, with the removable silicone components taken off for thorough cleaning. The combination of clear glass and coordinated silicone accents creates a versatile drinkware set for daily use.
