Double-Wall Borosilicate Glass
two clear walls of borosilicate glass with an insulating air gap between them keep hot drinks hot and cold drinks cold for longer, while the outer wall stays comfortable to hold and free of condensation

Glass Mug With Handle
a glass handle keeps fingers clear of a hot drink for a comfortable, secure hold, in the largest mug of the series, sized for lattes, cappuccinos, long coffees, and tea

Heavier Borosilicate Build
the glass is built up to 30% heavier than a standard double-wall glass, for a substantial, solid feel in the hand with enhanced durability and stability

Precisely Welded Rim
a precisely welded rim creates a thinner, refined edge compared to standard double-wall glasses, for added elegance and a cleaner drinking experience

Thermal Shock Resistant
the borosilicate build withstands temperature changes from −20°C to 150°C, so it handles iced drinks and freshly brewed coffee alike

BPA Free
made from chemical-free material for everyday use

The hero of the series. A double-wall glass is, on its own, a category baseline — every one keeps drinks hot or cold and looks like the drink is floating. What sets the Feller Double-Wall Glass Series apart is how it is built: a precisely welded, thinner rim and a noticeably heavier borosilicate body, engineered beyond a standard double-wall glass.

Precisely Welded Rim Design
the two glass walls are precisely welded at the rim to create a thinner, refined edge compared to standard double-wall glasses, for added elegance and a cleaner feel against the lip

Heavier Borosilicate Build (+30%)
built up to 30% heavier than a standard double-wall glass, the borosilicate body delivers a substantial, solid feel with enhanced durability and stability

Reliable Thermal Insulation
the welded double-wall construction holds an insulating air gap that keeps hot drinks hot and cold drinks cold for longer, while the outer surface stays comfortable to hold

Refined Drinking Experience
the combination of a thinner welded rim and a heavier, steadier body is what makes the glass feel considered in the hand, sip after sip

Made for Lattes & Long Coffees
at 330mL the pair of handled mugs — the largest in the series — suits lattes, cappuccinos, long coffees, and tea, with a handle that keeps fingers away from the heat and a clear double wall that frames a layered latte

Hot and Cold, Both at Home
the double-wall build keeps a hot drink hot and a cold drink cold for longer while the outside stays comfortable to hold, so it works year-round

Hand Washing Recommended
to protect the precisely welded rim, the handle, and the clarity of the glass, gentle hand washing is recommended *(guidance only — the box does not state dishwasher or microwave suitability; see Open flags)*

Handle With Everyday Care
double-wall glass is durable for daily use and thermal-shock resistant from −20°C to 150°C, but like all glassware it should not be subjected to sudden, extreme temperature swings beyond that range
