✅ Food-Grade Safe Material, Healthy & Odor-FreeThese coffee cups feature a food-grade 304 stainless steel inner tank, free of harmful substances like BPA and lead, ensuring no heavy metal leaching. They are safe to use with coffee, tea, water, hot drinks and other beverages, without altering their taste or flavor. The high-vacuum insulation layer between the double stainless steel walls provides long-lasting heat and cold retention, preventing burns with hot drinks and condensation with cold drinks, eliminating the hassle of slippery cups and wetting tables.
✅ Long-Lasting Heat & Cold Retention for All SeasonsWith professional vacuum temperature lock technology, they adapt to both hot and cold drinks:
- Heat Retention: Keeps hot coffee/tea warm at ≥60℃ for 4 hours, ≥50℃ for 8 hours, allowing you to enjoy warm drinks slowly at home or office.
- Cold Retention: Keeps iced coffee/cold drinks cold at ≤10℃ for 8 hours, ice-cold for up to 12 hours, maintaining the perfect taste of cold drinks in summer.
✅ Heat-Resistant & Scratch-Resistant Design, Minimalist & PracticalThe cup body features a matte black scratch-resistant coating that is fingerprint-proof and impact-resistant, keeping the cups looking sleek even with long-term use. The double-wall vacuum structure provides built-in heat resistance, so you won’t get burned holding the cup with hot drinks, no extra sleeve needed. The cup rim is polished stainless steel, smooth and comfortable to drink from, no scratches.
✅ No-Handle Minimalist Design, Versatile for Any OccasionThe minimalist no-handle style fits any setting, whether at home, office, camping, picnics or short trips. The compact shape allows for stackable storage to save space, and the non-slip base prevents tipping on desks for added safety.

✅ Durable & Easy to Clean for Long-Term UseThe food-grade stainless steel inner tank is corrosion-resistant and not prone to retaining coffee or tea stains, making it easy to clean with just water and a sponge, with no dead corners.
