The double-walled glass with bamboo lid is the signature accessory for lovers of perfectly served beverages. Its double-walled insulating technology keeps drinks at their ideal temperature for hours: hot drinks stay hot, cold drinks stay cold, with no condensation or burning to the touch. The natural bamboo lid adds an ecological and premium aesthetic dimension, while also protecting the drink from dust and insects during breaks in the office, on a terrace, or outdoors. Available in three capacities (250 ml, 350 ml or 450 ml) to suit all uses: long espresso, latte macchiato, tea, infusion, fresh juice, smoothie, cocktail. Thick and resistant glass designed for durable daily use. An object that transforms a simple drink into a moment of elegance — the "suspended drink" effect through the double wall creates a spectacular visual presentation that enhances even the most humble coffee.

Double wall technology: how does it work?
The double-walled glass consists of two blown glass walls separated by an air gap that acts as thermal insulation. This physical principle has been known since the late 19th century (thermos bottles have used it since 1892) and remains today the most effective passive insulation method for beverage containers.
Practical consequences of this technology: (1) the heat of the hot drink does not transfer to the outer wall → you can hold the glass with your bare hand without burning yourself; (2) the cold of the iced drink does not create condensation on the outside → no more puddles on the table and soggy coasters; (3) the drink's temperature is maintained 2 to 3 times longer than a classic glass → your coffee stays hot, your iced tea stays cold.
The "suspended drink" visual effect is a particularly spectacular aesthetic bonus: the drink appears to float in the center of the glass, creating a presentation worthy of specialty coffee shops.
Advantages of double-walled glass
All the uses of a good double-walled glass
Serving tip: to fully exploit the visual effect of the double-walled glass, opt for drinks that play on transparency and color: latte with the milk/coffee contrast, light green tea, orange juice, colorful smoothies, red wine. The "suspended drink" effect is all the more spectacular the more the drink contrasts with the transparent wall. For hot drinks, wait a few minutes before the first sip — the double wall maintains heat so well that the glass itself remains warm to the touch while the drink is still scalding hot inside. For entertaining, invest in several identical glasses of the same size to serve your guests consistently — the group effect on a table is particularly successful.
Care: hand washing is strongly recommended to preserve the double wall in the long term. Lukewarm soapy water with a soft sponge, immediate drying. Dishwasher is not recommended: repeated thermal changes can eventually weaken the junction between the two walls and create invisible micro-cracks. For the bamboo lid, clean with a slightly damp cloth only — never soak it or put it in the dishwasher, as this will cause it to warp. Occasionally apply a neutral food-grade oil (mineral oil, flaxseed) to the bamboo to preserve its suppleness and prevent drying. Store away from moisture.
Usage precautions: thick glass, but still fragile against violent shocks. Avoid abrupt thermal shocks (boiling water in a glass from the freezer, ice cubes in a hot glass). Not designed for microwave or oven use. Do not use on a direct hot plate. Keep out of reach of very young children. In case of cracks or damage, stop use immediately.
