Designed with a double-wall construction, this mug keeps hot beverages hot while the outer surface remains cool to the touch, reducing burn risk. The inner chamber is hand blown borosilicate glass, lighter than traditional glass yet durable and stable for daily use. The double walls create an insulating gap that helps minimize condensation and heat transfer to the exterior, making for comfortable handling during long sips. The mug is suitable for hot coffee and tea as well as cold drinks; insulation supports temperature retention without exterior sweating, which is convenient for everyday use. Borosilicate glass is easy to clean and resistant to thermal shock, and the material is safe for microwave use and dishwasher cleaning. The clean, clear appearance fits in at home or the office and supports a straightforward drinking experience without unnecessary decoration. For tasks such as morning coffee or a chilled beverage in the afternoon, the vessel offers reliable performance and longevity through regular household use. To maximize lifespan, handle with care, avoid rapid temperature changes, and wash before first use. With consistent care, the mug maintains clarity and insulating properties over time, supporting everyday drinkability across seasons and helping reduce condensation on cold beverages, and enabling comfortable handling wherever you pour. Size: large.
