Find your peaceful moment with JoyJolt Harbor Swirl double wall glass mugs, designed for home cooks and coffee lovers who appreciate both style and function. These 15-ounce mugs keep your hot coffee or tea warm while the double-wall insulation ensures the exterior stays cool to the touch—no more burnt fingers. The sculpted shape fits naturally in your hand, and the inner optic swirl adds a delicate texture that dances as you pour, turning your daily coffee ritual into an intentional, grounding act.
Each mug in this set of two is crafted from durable, lead-free borosilicate glass that resists thermal shock. The 15-ounce capacity is perfect for a generous latte, a full cup of tea, or a cozy hot chocolate. The double-wall insulation works for both hot and cold drinks, maintaining temperature longer than single-wall cups. These mugs are dishwasher and microwave safe for effortless care, and they arrive in a secure gift box with padding, ready for gifting to yourself or a friend. Stand approximately 5.1 inches tall with a 3.3-inch diameter.
Unlike ceramic mugs that conceal your drink or single-wall glass that gets too hot, these insulated mugs let you see the color of your brew while keeping your hands comfortable. The borosilicate glass is stronger than soda-lime glass used in cheaper alternatives, and the double-wall design prevents condensation on cold drinks. Many similar mugs crack under heat, but our thermal shock resistance ensures long-lasting use.

Yes, the borosilicate glass handles hot beverages up to 150°C (302°F) well. The double wall keeps the exterior cool to the touch, so your hands stay comfortable while your coffee stays warm longer than in a ceramic mug.
Yes, they are dishwasher safe. Use a gentle cycle and avoid abrasive detergents to maintain the glass clarity. They are also microwave safe for reheating drinks, but avoid empty microwaving.
Each mug holds 15 fluid ounces (444 milliliters), perfect for a generous serving of coffee, latte, tea, hot chocolate, or even cold beverages. The double-wall insulation also works for iced drinks.
Yes, this product includes a set of two mugs. They arrive nestled in a padded gift box, making them ready for gifting to coffee lovers, housewarming hosts, or as a treat for yourself.
No, the optic swirl texture is integral to the glass, not applied on the surface. It is molded into the borosilicate glass during manufacturing, so it will never fade, peel, or wear off, even after frequent dishwasher use.
Bought these as a housewarming gift. The swirl pattern is mesmerizing. My friend loved them. Double wall works great—coffee stays hot.
These mugs are beautiful. The glass is thick but not heavy. I drink my coffee slowly and it stays warm for 20 minutes. No complaints.
They look amazing on the shelf. But I'm a bit nervous about dropping them—the glass feels thin even though it's double wall. So far no issues.
Got these for my morning coffee. They keep the coffee hot and the outside cool to touch. Love the swirl design. Worth it.
Bought for my sister's birthday. She's a coffee snob and she loved them. Said they're the best mugs she's owned.
They look nice, but I think the price is a bit high for two mugs. The insulation is good though. For the look, it's okay.
Love the design, love the insulation. Only thing is the base is a little small—tips easily if you're not careful. But overall happy.
