Hlukana Double Walled Glass Coffee Mugs Review: Insulation Tested

Looking for a set of double walled glass coffee mugs that look great and keep your hands from getting burned? The Hlukana mugs caught my attention with their hand-blown borosilicate glass construction and a price tag that undercuts most competitors.

The Hlukana Double Walled Glass Coffee Mugs come as a set of 2, each holding 8 oz of your favorite beverage. Made from heat-resistant borosilicate glass rated up to 150°C (302°F), these insulated mugs feature an ergonomic handle and a clear double wall design built for cappuccino, latte, espresso, and americano.

I’ve been using this coffee mugs set daily for my morning espresso routine to see how the insulation, durability, and comfort hold up under real-world conditions.

The short version? These mugs with handle deliver where it counts, though there are a few trade-offs worth knowing about before you buy.

What I Liked

Double Wall Insulation That Works

The standout feature of these glass coffee mugs is the double wall insulation, and it delivers. I poured freshly boiled water into the mug and touched the outer wall immediately — it stayed completely cool to the touch.

This prevents hand burns from freshly extracted espresso or heated milk froth, which is the entire reason you buy double walled glass over regular mugs. The insulating air pocket between the two walls also keeps your coffee hot noticeably longer than a standard ceramic cup. If you prefer the heft and warmth of thick ceramic over glass, the Coffeezone Double Espresso Coffee Cup and Saucer takes a similar approach with bone china walls designed for heat retention.

The Floating Coffee Effect

One of the unexpected perks of clear coffee mugs like these is the visual effect. You can see the crema and milk swirl through the transparent double wall, creating the illusion that your drink is floating inside the mug.

Pour a cappuccino or latte into these and the layered colors look striking. It turns a regular morning coffee into something that feels more intentional. Pairing these mugs with a quality brewer like the Moccamaster KBGV Select Coffee Maker ensures the coffee inside tastes as good as it looks through the glass.

Comfortable Handle Design

The handle on these mugs fits three fingers comfortably for a secure grip. This is a significant improvement over many double walled glass coffee mugs that either skip the handle entirely or include one too small to use.

I appreciated having a proper handle, especially when the mug was full of hot liquid. It makes these mugs for cappuccino and espresso feel practical rather than just decorative.

Borosilicate Glass Durability

These are constructed from borosilicate glass, the same material used in lab equipment. The glass is 100% lead-free and BPA-free, and it feels light yet sturdy in the hand.

After weeks of daily use, my set of 2 mugs still look clear with no chips, cracks, or cloudiness. The 8 oz hand-blown construction gives them a quality feel that matches more expensive alternatives.

Solid Value for the Price

At under $12 for a set, this product punches above its weight. The quality matches mugs costing two to three times as much from established brands like Bodum.

Amazon reviewers have noted these are on par with higher-end alternatives, and I agree. For the price of a single premium double walled mug, you get two that perform just as well. That same impressive value extends to kitchen tools, where the Snuvid Teak Wood Cooking Utensils 12-Piece Set offers a complete teak set for under $30.

What Needs Improvement

Hand Wash Only Is Non-Negotiable

Like most double walled glass mugs, putting these in the dishwasher risks trapping water between the walls. Reddit users across multiple threads confirm this is the most common failure point for double walled glassware, and Hlukana’s own care instructions specify hand wash only.

The 8 oz Capacity Feels Small for Some Drinks

If your typical morning coffee is a 12 or 16 oz pour, these will feel undersized. The 8 oz size is ideal for espresso, cappuccino, and cortado, but anyone who drinks large americanos or drip coffee will want something bigger.

Handle With Care — Glass, Not Ceramic

While the borosilicate glass is tougher than standard glass, these mugs are still more delicate than your average ceramic coffee cup. Some Reddit users have reported similar double walled mugs cracking from thermal shock. I haven’t experienced this, but I do treat them more gently than my ceramic mugs.

Minor Manufacturing Imperfections Are Possible

Since these are hand-blown, occasional small air bubbles in the glass are normal. One of my two mugs had a tiny bubble that doesn’t affect function but is visible up close. This is common across hand-blown double walled glass coffee mugs at this price point.

How It Compares

The double walled glass coffee mugs market has several established players. Here’s how the Hlukana set of 2 stacks up against the competition.

Bodum Pavina is the name most people know in this category. Bodum’s double walled glass mugs are widely available and come in more size options, but they typically cost $20-30 for a set of 2. The glass quality and insulation performance are comparable, making the Hlukana a strong budget alternative. Choose Bodum if you want a trusted brand name with wider retail availability.

JoyJolt Savor is a popular Amazon competitor at a similar price point. JoyJolt offers clear coffee mugs in a wider range of sizes, including 13.5 oz options for those who need more capacity. The insulation and glass quality are similar. Choose JoyJolt if the 8 oz size is too small for your needs.

De’Longhi Double Wall Thermal Glasses sit at the premium end. Backed by a recognized espresso machine manufacturer, these cost roughly three times the Hlukana price. The build quality is marginally better, but the insulation performance difference is minimal. Choose De’Longhi if you want brand prestige and already own their espresso machines.

For most coffee mugs buyers on a budget, the Hlukana mugs deliver the same core benefit — insulated double walled glass with handle — at a fraction of the premium price.

Final Verdict

The Hlukana Double Walled Glass Coffee Mugs deliver on their core promise: insulated, clear glass mugs that keep your hands cool and your coffee hot, at a price that undercuts the competition.

I’m giving them a 4.3 out of 5.

The hand-wash-only requirement, compact 8 oz capacity, and inherent fragility of glass keep this product from a top score. But the effective insulation, comfortable handle, and remarkable value for a set of 2 make these easy to recommend for most espresso and cappuccino drinkers.

Bottom line: If you want double walled glass coffee mugs that perform like brands costing twice as much, these are a smart buy.
