Key Features

Premium 316 Steel Interior

Food-contact surfaces use 316-grade stainless steel, which contains molybdenum for superior corrosion resistance compared to standard 304 steel, particularly against acidic beverages and salt exposure.

Vacuum Double-Wall Construction

Air evacuated between inner and outer steel walls blocks conductive heat transfer. Cold drinks stay chilled and hot drinks retain heat without exterior condensation or surface heat.

Spring-Loaded Pop-Up Straw

Thumb-press button deploys a protected drinking straw through the lid. Closed position seals the opening to reduce spills during transport or storage.

Made For

Daily commuters needing spill-resistant portable drinkware
Gym users carrying cold water or protein shakes
Drivers who prefer straw access while keeping both hands on the wheel
Office workers who want desk-stable insulated cups

Not Suitable For

Dishwasher cleaning (hand wash only to preserve vacuum seal)
Microwave heating (metal construction)
Carbonated beverages (pressure buildup in sealed lid)
Oven or stovetop use

Two Graphic Designs

Choose between Overture Overlord Cup design or Big Ice Master Cup graphic. Both variants use identical construction and insulation performance, differing only in exterior printed artwork.

Common Questions

What makes 316 stainless steel different from regular stainless steel?

316 grade contains 2-3% molybdenum, which increases resistance to chlorides, acids, and pitting corrosion. This matters for coffee, citrus drinks, and saltwater environments where standard 304 steel can degrade faster.

How does the pop-up straw mechanism work?

Press the thumb button on the lid to spring the straw upward through a sealed opening. Release or press again to retract the straw back into the closed lid position for transport.

Can I put this cup in the dishwasher?

No. Dishwasher heat and detergent pressure can compromise the vacuum seal between the double walls. Hand wash with warm soapy water and air dry.

Does the insulation prevent condensation on the outside?

Yes. The vacuum layer between inner and outer walls stops heat transfer, so cold drinks do not cause exterior condensation and hot drinks do not make the outer surface too hot to hold.
