Frequently Asked Questions

Thanks to vacuum insulation, the HEY SAHNI cup keeps drinks hot for up to 8 hours and ice cold for up to 12 hours.

All HEY SAHNI cups are made from premium 18/8 stainless steel with double-wall vacuum insulation. Food-safe, rust-resistant, BPA-free, and built to last.

Yes — all HEY SAHNI products are 100% BPA-free and made from food-grade 18/8 stainless steel.

The HEY SAHNI cup holds 350 ml (12 oz) — the perfect size for a coffee to go, latte, matcha, or your favourite drink.

Any drink you like — coffee, latte, cappuccino, matcha, tea, iced coffee, smoothies, or even a glass of wine at a picnic in the park.

The cup is spill-proof — it won't spill if tipped over or lightly shaken. It is not fully leak-proof, so we recommend keeping it upright and not packing it full in a bag.

The stainless steel body is dishwasher safe, but we recommend hand washing to keep the colour coating looking its best. The lid is fully dishwasher safe.

Hand wash the cup with warm water and dish soap. The lid can go in the dishwasher. A toothbrush works great for cleaning underneath the sliding opening.

Make sure the lid is open before placing it on a cup with a hot drink. Press down firmly until it seats securely, then slide to close. With boiling water, take care as steam can dislodge the lid.

HEY SAHNI cups are a sustainable alternative to disposable cups. In Germany alone, 320,000 single-use cups are thrown away every hour. One reusable stainless steel cup saves hundreds of disposables over its lifetime — and many cafés offer a discount when you bring your own.
