Wholesale 8oz/10oz/12oz SS Vacuum Insulated Tumbler with Slider Lid OEM Coffee Cup Manufacturer

Premium Double Wall 304/316 Stainless Steel Lowball Tumbler

Upgrade your drinkware lineup with our best-selling vacuum insulated lowball tumbler series, available in three standard B2B capacities: 8oz (240ml) mini pocket size, 10oz (300ml) mainstream best-seller (as pictured), and 12oz (360ml) office-friendly volume. Engineered with a double-wall vacuum structure, these stainless steel tumblers keep beverages hot (above 60°C) for 6–8 hours and ice-cold for 12–14 hours without exterior condensation, making them perfect for iced coffee, whiskey, sports drinks, and daily hydration.

The cup body features a food-grade 304/316 (premium 316L) stainless steel inner liner and a 201 stainless steel outer shell finished with a durable matte powder coating that resists chipping and fading. Each tumbler is equipped with a BPA-free Tritan/PCTG transparent slider lid (withstands up to 100°C) and a food-grade silicone seal to prevent leaks, even when inverted. As a direct factory in Zhejiang, China, we specialize in OEM/ODM bulk orders including laser-engraved logos, silk-screen printing, heat-transfer graphics, full Pantone color matching, and custom white/gift box packaging. With an MOQ of just 100 pieces for stock colors and 500 pieces for new molds, we support ship worldwide.
