Greens Steel BEAST Insulated Coffee Mug 900 ml Arctic White — Double-Wall Vacuum, Pop-Up Lid

The Greens Steel BEAST 900 ml insulated coffee mug is a double-walled 304 stainless steel travel tumbler that keeps drinks hot or cold while including two reusable straws, a cleaning brush, and an upgraded pop-up lid.

This 900 ml Arctic White BEAST tumbler pairs durable 18/8 food-grade stainless steel with a double-wall vacuum design and a splash-proof pop-up lid to preserve beverage temperature and taste. Built for repeated daily use, the cup’s electro-polished interior prevents metallic aftertastes while the powder-coated exterior resists scratches and sweat. The package also includes two unbreakable straws (one curved, one wide), a straw brush, and attractive gift-boxing—positioning this mug as both a practical commuter companion and a premium reusable gift.

How well does the BEAST keep coffee hot or iced?

The BEAST uses a precision double-wall vacuum that minimizes heat transfer and maintains temperatures longer than single-wall bottles. While exact hold times vary by initial temperature and ambient conditions, users can expect excellent all-day performance compared with many standard tumblers.

• Double-walled vacuum insulation reduces heat exchange.
• Splash-proof pop-up lid limits temperature loss and spills.
• 900 ml capacity reduces frequent refills, helping retain heat.
• Electro-polished interior prevents flavor transfer over time.

Is the BEAST durable enough for daily travel?

Yes—the BEAST is built from premium 304 (18/8) food-grade stainless steel for corrosion resistance and structural strength. The powder-coated finish resists scratches and keeps the exterior sweat-free, while the upgraded lid and included straws are made to withstand repeated use.

• Solid 304 stainless steel construction for long-term durability.
• Powder coat finish resists chipping and prevents condensation.
• Unbreakable reusable straws and straw-cleaning brush included.
• Gift-boxed packaging protects the cup during shipping and storage.

How easy is the BEAST to clean and maintain?

Cleaning is straightforward: the electro-polished interior resists residue, and the pop-up lid is designed for quick access. For the straws, the included brush lets you reach inside and remove trapped debris; handwashing the lid and straw is recommended for longevity.

• Electro-polished interior discourages flavor retention and stains.
• Pop-up lid disassembles for simple rinsing or handwashing.
• Straw brush cleans both curved and wide straw profiles effectively.
• Powder coat exterior is easy to wipe clean without leaving streaks.

What extras come with the BEAST and why do they matter?

The BEAST bundle includes two different reusable straws, a straw brush, and an upgraded pop-up lid, offering more versatility than a basic tumbler. These accessories make the mug better suited for multiple drink types—from coffee to shakes—and simplify cleaning and daily handling.

• Curved straw for sipping water and hot beverages comfortably.
• Wide straw for thicker drinks like smoothies or protein shakes.
• Straw brush ensures hygienic cleaning inside narrow openings.
• Upgraded pop-up lid provides splash resistance and easy drinking access.

Who is this for: The BEAST 900 ml insulated mug fits commuters, remote workers, gym-goers, and anyone who prefers a large, single reusable cup for coffee, tea, water, or blended drinks. It’s suited to buyers who want a robust, taste-preserving tumbler with practical extras—like dual straws and a cleaning brush—packaged as a ready-to-give gift. If you need a high-capacity, low-maintenance travel cup that looks clean and performs reliably, the Greens Steel BEAST is designed to meet those needs.
