Borosilicate Glass Coffee Mugs Set of 4 - Double Walled 12.5oz

In this review the focus is on a set of four clear double-walled glass mugs that aim to elevate everyday hot and cold drinks. The bottom line: these 12.5oz borosilicate cups are best for someone who wants visually striking, lightweight drinkware that stays cool to the touch and showcases latte art while handling routine dishwasher and microwave use. The review highlights safety, capacity, and appearance as the biggest reasons to buy, with honest notes on durability from other buyers.

Key Features

• Double-walled borosilicate: The mouth-blown borosilicate construction provides thermal insulation so drinks stay hotter or colder longer while the exterior remains cool to the touch.
• Clear suspended effect: The double-layer design makes the beverage appear suspended, improving presentation and highlighting coffee flower drawing or latte art.
• 12.5oz capacity: Each cup holds 12.5 ounces to the rim, a practical size for espresso-based drinks, tea, or a small soup bowl for everyday use.
• Small hole safety design: A sealed small round hole at the bottom prevents bursting during temperature changes by allowing the glass to breathe while remaining watertight.
• Microwave and dishwasher safe: The cups are suited to routine reheating and easy cleaning in the dishwasher, fitting into a busy kitchen rhythm.
• Gift-ready packaging: Thick protective packaging and optional gift box make the set suitable as a present for housewarmings or special occasions.

Who It's For

These glass mugs suit home baristas, latte lovers, and anyone who values presentation; the clear double-wall makes foam art visible and gives drinks a modern look. They are also good for households that need microwave- and dishwasher-safe cups that remain cool on the outside.

Customers who need ultra-rugged, daily commercial use drinkware or who are extremely concerned about accidental breakage should consider sturdier alternatives, since some reviewers reported breakage within weeks despite many others praising the build and lightweight feel.
