The glastal Stackable Glass Cups 4 oz Espresso Cups Double Walled set is worth buying if you want dishwasher-safe, double-walled glass that actually looks as good as your morning coffee ritual deserves. Four cups, 4 ounces each, hand-blown, and sturdy enough that I didn’t baby mine. Buy it for the daily espresso habit, skip it if you need bigger mugs.

How this review was made: written from my own video review of this product. Every opinion here is my own, from using it myself.
Quick Verdict
I had one of the four cups already dirty before filming, because I’d used it so much I grabbed it first thing. They’re double-walled, 4 ounces, and went straight into the dishwasher without drama.
Buy if you:
- drink espresso or short pours and want cups sized to match
- like the visual of coffee floating in a double-walled glass
- want stackable glasses that don’t eat counter space
- need a gift for a coffee or tea person
Skip if you:
- drink full mug-size coffee, not shots or small pours, because 4 oz fills up fast
- are rough with glassware, since the brand itself warns they’re brittle
- want something for kids’ use given the handwash-recommended glass

I Already Had One Dirty Before I Finished Unboxing
I got the glastal Stackable Glass Cups 4 oz Espresso Cups Double Walled set and only had three of the four in frame when I started filming, because I’d already used the fourth one. That’s not me stalling for content, that’s just what happened. I love it. They’re so durable, and I didn’t think twice about tossing one in the dishwasher.
People Assume Stackable Means Flimsy. It Doesn’t.
Most stackable glasses are thin because thin nests cleanly, which is exactly why they’re miserable to hold with a hot drink inside. The double wall adds real thickness between the inner and outer glass, which is the same reason the cup stays cool enough to hold even with hot coffee inside. I held mine right after pouring and it wasn’t a problem, no scrambling for a napkin or a coaster to protect my hand.
What’s Actually Inside the Double Wall
Borosilicate glass is the material doing the real work here, rated for -30°C to 150°C swings, which is why it goes from freezer to hot espresso without cracking on you. The double-walled construction is what gives it that optical suspension look, where the coffee appears to float inside the glass with no visible outer cup touching it. I filled mine with one whole cup of coffee, then topped it off a little more, then added a splash of milk, and you could watch the layers sit inside the glass instead of just looking at a solid brown cup. That’s the “experience” part the brand markets, and it’s the one claim I’d actually back up after using it.
What the Set Actually Buys You
Four hand-blown glass cups, each 4 ounces, with 18 months of product support behind them, that’s the trade for the price. It’s not a runaway bestseller, but it’s been moving steadily enough that stock hasn’t been an issue when I checked. Pricing today is sitting a touch above its usual three-month range, so I’d check the current price at the link before deciding if this is the week to grab it. For four hand-blown, double-walled glasses with a gift box included, that’s less per cup than most single espresso glasses from competitors I’ve seen, and those don’t stack or come ready to wrap.
One Thing to Know Before You Order
These are 4 ounces, which I measured against my own phone for scale in the video, and that’s small. If your normal coffee order is a 12 oz mug, this isn’t a replacement for your everyday cup, it’s built for espresso, a short latte, tea, or dessert portions. I personally do one full pour of coffee, add a bit more, then milk on top, and it works because I’m not trying to fit a full mug’s worth in there. The brand does call out that all glass articles are brittle and to be careful washing them, so even though mine have held up fine, I’m not pretending they’re unbreakable.
Pros
- Durable enough that I didn’t baby mine after regular use
- Dishwasher-safe, though hand washing is recommended
- The double-wall effect genuinely looks as good as it does in photos
- Stackable design actually saves counter space
- Good gift presentation with the included box
Cons
- 4 ounces is small if you drink full mugs of coffee, not just espresso
- Glass is brittle by the brand’s own admission, so care is needed
- Hand washing is recommended over the dishwasher despite being dishwasher-safe
Frequently Asked Questions
Can stackable glass cups go in the freezer?
Yes, the borosilicate glass in this set is rated for -30°C to 150°C, so the freezer compartment is fine. Just don’t jump straight from freezing cold to boiling hot in one move, that kind of shock is what cracks any glass regardless of rating.
Are replacement cups available if one breaks?
The listing mentions 18 months of product support, which typically means you can reach out to the brand if something arrives damaged or fails early. I’d keep your order confirmation handy since that’s usually what support asks for.
Will these stack with other glassware I already own?
They’re designed to nest with each other within the same 4-piece set, not necessarily with glasses from a different brand or shape. If you’re trying to consolidate cabinet space, buy enough of the same set rather than mixing it with other stackable glass cups you already have.
Is this set too small to use as everyday water glasses?
Yes, at 4 ounces each these are sized for espresso, short lattes, tea, or dessert portions, not for sipping water through the day. If you want something for water you’d need a larger stackable glass set, this one is built around small pours.
