Coffee lovers, office managers, and event planners - this 12-pack of 20oz stainless steel tumblers is the bulk solution you've been waiting for! These vacuum insulated tumblers keep your drinks at the perfect temperature for hours - hot beverages stay warm for up to 3 hours, while cold drinks and ice remain chilled for an impressive 9 hours. The black powder-coated exterior isn't just stylish (with that elegant polished frosted surface), it's also sweat-proof and non-slippery for comfortable handling. Inside, the electro-polished interior prevents flavor transfer, so your morning coffee tastes like coffee, not yesterday's smoothie. These BPA-free, food-grade tumblers are built to last with durable stainless steel construction that's hard to break, making them perfect for daily use in offices, cafes, events, or at home. The splash-proof lids feature convenient sip-through openings, and the design is easy to clean by hand (just remember they're not microwave-safe). Whether you're stocking an office kitchen, hosting an event, or just want matching drinkware for your family, this bulk set delivers exceptional value. They're versatile enough for coffee, tea, smoothies, water, or any beverage you prefer. The set makes a fantastic gift for holidays, corporate events, or anyone who appreciates quality drinkware. Your customers, employees, or family members will love having their own personalized tumbler that actually maintains drink temperatures properly throughout the day!
