✅ Food-Grade Safe Material, Healthy & Odor-FreeThis vacuum tumbler features a food-grade 304 stainless steel inner tank, free of harmful substances like BPA and lead, ensuring no heavy metal leaching. It is safe to use with beer, coffee, juice, cold drinks and more, without altering the taste or flavor of your beverages. The high-vacuum insulation layer between the double stainless steel walls completely blocks heat transfer, providing long-lasting cold retention while preventing condensation on the outer wall, eliminating the hassle of slippery cups and wetting tables or books.
✅ Long-Lasting Cold Retention for Ultimate RefreshmentDesigned specifically for cold drinks with professional vacuum cold-lock technology, keeping your beverages ice-cold for hours:
- Cold Retention: Keeps iced beer, soda and juice cold at ≤10℃ for 12 hours, ice-cold for up to 24 hours, perfect for camping, picnics and game nights.
- Hot Drink Compatibility: Also suitable for holding hot coffee, warm water and other hot beverages, with the double-wall structure providing heat insulation to prevent burns and ensure a comfortable grip.
✅ Sweat-Free & Non-Slip Design for a Clean ExperienceThe matte non-slip coating on the cup body is scratch-resistant, wear-resistant and provides a secure grip. The double-wall vacuum structure achieves a sweat-free, condensation-free effect, keeping the cup body dry at all times, so it won’t leave water rings on desks, car cup holders or picnic mats. The minimalist handleless design with a wide mouth is easy to hold and fits most standard car cup holders, making it stable for commuting and road trips.

With its sleek appearance and practical cold-retention, sweat-free design, it is a must-have for beer lovers, coffee enthusiasts and cold drink fans. It is also perfect for corporate custom branding, event giveaways and holiday gifts, as it can be printed with logos for brand promotion.
✅ Durable & Easy to Clean for Long-Term UseThe food-grade stainless steel inner tank is corrosion-resistant and not prone to retaining tea or coffee stains, making it easy to clean with just water and a sponge, with no dead corners. It is also dishwasher safe (check product specifications for details). The cup rim is smoothly polished for a comfortable, scratch-free drinking experience. The thickened non-slip base prevents tipping on desks and campsites, extending the service life of the tumbler.
