520 & 620ml 304 Steel Tumbler | Dual-Size Commuter Cup — Factory Direct
Features
-
SUS 304 Matte-Coated Interior : The interior bears the stamped "SUS 304" certification alongside a matte dark grey coating that resists staining, odor absorption, and surface micro-scratching far more effectively than standard mirror-polish alternatives.
-
Double-Wall Vacuum Insulation : The PP outer shell and 304 steel inner wall sandwich a vacuum-sealed air gap — keeping cold drinks cold for 12+ hours and hot drinks hot for 6+ hours without any exterior condensation or heat transfer.
-
Rotary Silicone Valve Lid : The clear PC lid features a color-matched rotary mechanism that opens and closes the drinking aperture with a quarter-turn. A silicone plug seals the hole when closed, preventing evaporation and spills during commute movement.
-
Ergonomic 620ml Waist Curve : The larger variant features a precision-molded concave waist band — reducing the effective grip diameter and preventing the cup from slipping during one-hand carry or driving use.
-
Bent 304 Steel Straw : The included bent steel straw is sized to reach the bottom of both cup variants — durable, dishwasher-safe, and a direct signal of product quality versus cheaper plastic alternatives.
B2B FAQ
Q: Can both sizes be ordered as a mixed set?
A: Yes. The 520ml and 620ml can be mixed within a single MOQ — both colors and both sizes together if needed.
Q: Is the silicone valve lid leak-proof for bag carry?
A: Yes. When the rotary valve is in the closed position and the silicone stopper is engaged, the lid provides a reliable seal for bag carry and mild tilting. It is not designed for fully inverted storage.
Q: Is the matte coating food-safe?
A: The interior matte coating is a food-contact-certified layer applied to the 304 steel surface. The exterior matte lacquer is on the PP outer shell only and does not contact the beverage.
