Pour a drink into an ordinary glass and it does the obvious thing. It sits there. Flat, still, waiting.

The Helix is built from two separate walls of borosilicate glass. The outside is smooth and straight. The inside is twisted into a deep spiral that runs from the base all the way to the rim, so your drink has to climb it. An iced latte becomes a ribbon of dark and light winding up through the glass. Matcha spirals green through cold milk. The same coffee you make every morning suddenly looks like something you queued for.

Two Walls, One Very Good Reason

✦

A Sealed Layer of Air

Between the two walls sits a sealed pocket of air, and air is a poor conductor of heat. That single fact is what keeps a hot coffee hot for longer and an iced drink cold long past the point where a normal glass has given up.

◦

It Does Not Sweat

Because the cold never reaches the outer wall, the outside stays dry. No puddle on the desk, no ring on the wood, no damp coaster stuck to the bottom when you lift it.

□

Comfortable to Hold, Full of Anything

The same air gap works in the other direction. Fill it with a fresh pour and the outer wall stays comfortable in your hand, which is exactly why this glass does not need a handle.

◉

High Borosilicate Glass

The same glass used in laboratory equipment and professional coffee gear. It handles the swing from a hot pour to a glass packed with ice without complaint, and it stays clear rather than clouding over time.

The Spiral Is Not Just Decoration

The twist runs through the inner wall, which means the drink itself takes the shape rather than being hidden behind a pattern. Layers separate and curl. Espresso falls through milk in slow spirals instead of a straight line. Ice sits caught in the turns. From the outside the glass stays perfectly smooth, so all of that movement reads through clean glass with nothing in the way.

Why There Is No Handle

A handle exists to keep your fingers away from hot, thin glass. A sealed double wall removes that problem entirely, so the handle becomes something to store, something to knock, and something to break.

What you get instead is a clean cylinder that sits closer together in a cupboard, stacks neatly in a dishwasher, and looks like one continuous piece of glass from every angle.

Coffee First, Everything Else After

At 280ml this is a proper coffee size. A double flat white, a cortado with room, an iced latte over a decent amount of ice, a cold brew. It is not a novelty shot glass and it is not a bucket. It also happens to be very good for matcha, sparkling water with a slice of lemon, iced tea, or a plain glass of water on the bedside table.

Four, Because One Is Never Enough

Sets of two run out the moment someone visits. Four covers a table, covers a weekend, and covers the days when half of them are in the dishwasher. Buy one set and your morning coffee stops being a compromise on whatever mug was clean.

Questions

Do these come with straws?

No. The set is four glasses on their own. They work perfectly well with any standard straw if you use one, and just as well without.

Will the outside get hot if I pour hot coffee in?

No. That is the whole point of the sealed double wall. The heat stays in the inner chamber with your drink rather than moving out to the surface you are holding.

How big is 280ml really?

A little under a standard can of soft drink. It takes a double flat white or a cortado comfortably, and an iced latte with a proper amount of ice. If you drink very large mugs of filter coffee, this will feel neat rather than generous.

Can they go in the dishwasher?

Yes, on a normal cycle. Stand them upright on the top rack where they will not knock against heavier items.

Is double walled glass fragile?

It is glass, so it will not survive a drop onto a tiled floor. What borosilicate handles far better than ordinary glass is thermal shock, which is the thing that actually cracks most glassware in everyday use.

Why is there no handle?

Because the double wall means you do not need one. A handle on a glass like this would add a weak point and take up cupboard space for no benefit.
