JoyJolt Savor Double-Wall Glass Coffee Mugs — 13.5 oz Set of 2
Product description
Savor familiar comfort with a contemporary twist: this set includes two 13.5-ounce double-wall glass mugs with attached handles, modeled on the classic diner cup shape. Each mug measures about 4.5 inches tall and roughly 4 inches across at its widest point, offering a generous capacity for coffee, tea, lattes, or cold drinks.
The cups are mouth-blown and formed from temperature-resistant borosilicate glass, featuring a vacuum-style double-wall that insulates your beverage. That construction keeps hot drinks hotter and cold drinks colder while leaving the outer surface comfortable to hold. The design lets you cradle the mug without burning your hands and shows layered drinks beautifully.
These insulated glasses are lead-free and naturally BPA-free. They're rated safe for use in the refrigerator, freezer, microwave, oven, and dishwasher, though many owners prefer hand-washing to extend the life of the glass. The set arrives securely wrapped in a gift-ready box and is backed by a 12-month guarantee for peace of mind.
Use them for morning coffee, an evening tea, or iced beverages—the double-wall keeps temperatures separated so ice won’t quickly melt and hot drinks retain warmth. For extra heat retention with very hot beverages, some users pre-warm the mug with hot water before pouring in coffee or tea.
Because they’re glass, treat them with some care: avoid extreme thermal shocks and rough handling. When treated gently these mugs provide an attractive, insulated drinking experience that evokes diner nostalgia while remaining modern in performance.

VerdictThese 13.5 oz double-wall glass mugs blend nostalgic diner styling with modern thermal performance.

They’re lightweight and elegant, but require a bit of care because glass is naturally more fragile than ceramic or metal. If you want insulated, tran

Water between the walls after little use
I stored these for months and only recently started using them; after a few uses one developed water between the walls with no visible crack. I avoid sudden temperature changes, so I’m unsure how it happened.

Handle stays cool in the microwave
I reheat coffee in the microwave and the handle never gets hot. The clear glass shows layers of coffee and foam nicely. I hand wash them and handle with care.

Two years later and still reliable
After two years of daily use and hand washing these mugs have held up and kept my coffee and green tea hotter for longer than regular cups. I haven’t had any seepage into the inner wall like with some insulated glasses. Pro tip: pour hot water in to pre-warm before adding coffee for even better heat retention.

My go-to morning mugs
I reach for these every morning. They keep coffee warm longer, don’t burn my hands, and have a classy look. Would purchase again.

Love them but dishwasher risk
They keep drinks hot and the exterior stays cool, but three broke in the dishwasher over time despite being listed as dishwasher-safe. I hand wash the rest now and wish they’d held up better.

More like a small bucket than a cup
Well packaged, but note these are quite large—bigger than a typical cup.

Stylish and worth careful handling
Love the sleek look and insulation. Yes, they’re glass and require care—I broke two myself—but I bought more because the experience is worth it. Lightweight and elegant.

Very light and became our daily favorite
They felt fragile at first, but we kept them and now use them every day. Guests can’t believe they’re glass because they’re so light. We hand wash them and have reordered after one eventually broke.

Easy to hold, great for arthritic hands
Comfortable grip and a good capacity that fits under my espresso machine. Smooth lip and not bulky—keeps coffee warmer longer. Recommended.
