Recovered cork band: A band of 100% recovered cork insulates your hand from the heat of a fresh coffee and gives the glass a warm, natural grip that does not slip. Because the cork is recovered material, the part you hold every day is made from something that would otherwise have been waste. Tempered glass, pure taste: Tough tempered glass means coffee, tea and cold brew taste exactly as they should, with no plastic aftertaste and no lingering flavours however often you refill it. Clear glass also shows the pour, the crema and the exact strength of your coffee, which is why baristas prefer serving into glass. Splashproof press-fit lid: The lid pushes on and seals against splashes, so the cup rides safely upright from the cafe counter to your desk and a car cup holder. The lid and cork band lift off completely, so there are no hidden seams or trapped seals where coffee oils and milk can build up. Built to be repaired, not replaced: The glass base, press-fit lid, plug and cork band are all available as separate spare parts, so one worn component does not end the cup, and manufacturing defects are covered by warranty. Top-rack dishwasher safe, independently lab tested every year, and free from BPA, BPS, phthalates, lead and cadmium. Barista-standard sizing: Made to standard cafe measures, so your barista pours exactly the drink they would in a single-use to-go cup. No guesswork at the counter, no half-full reusable coffee cup, and no awkward conversation about whether your cup is the right size for a regular latte or flat white.
