Advanced Double-Layer Vacuum Insulation with 24-Hour Cold and 12-Hour Heat Retention

Precision-engineered double-layer vacuum insulation in this insulated tumbler 40oz keeps drinks cold for a long time. Vacuum insulation technology creates an air barrier that prevents temperature changes from affecting the inside. 

The advanced thermal engineering makes sure that your coffee stays hot during long journeys in the morning and your ice water stays cold during long outdoor activities in the afternoon. This 40-ounce insulated mug keeps drinks hot or cold from the first sip to the last drop.

Premium SUS304 Stainless Steel Construction with FDA Certification

Premium SUS304 (18/8) food-grade stainless steel is used for high-quality building applications because it is very durable and won't alter the taste. The 18% chromium and 8% nickel mix makes it highly resistant to rust and prevents metallic flavors from transferring to the beverage. 

The FDA-approved design ensures that all types of drinks, including acidic beverages and hot liquids, are safe to store for long periods. The SUS304 surface is non-reactive, so it doesn't stain, retain odors, or support the growth of germs. It also keeps the original flavor of your drinks. For long-term, daily use with peace of mind, this insulated 40-ounce mug is constructed to meet the strictest safety standards.

Optimized 40-Ounce Capacity with Precise Dimensions for Insulated Tumbler 40oz

There is a large 40-ounce (1200ml) size that holds the most water and keeps you hydrated all day without refilling. The exact measurements of 4.25" x 5.75" x 9.76" (108 x 146 x 248 mm) make it big enough to hold a lot of liquid volume. The 1.1-pound (0.505kg) weight makes it easy to carry, even though it can have a lot of stuff.

The tumbler's perfect size balances capacity with ease of handling, so even when it's full, it's still easy to handle. A diameter of 4.25 inches makes it compatible with normal cup holders, and a height of 9.76 inches makes it easy to carry. 

Leak-Proof Silicone Gasket System with 360-Degree Shake Protection

The carefully designed silicone gasket system prevents leaks by sealing the lid's edges. The high-quality silicone remains flexible across a wide temperature range and maintains consistent closing pressure, preventing spills during transport. The gasket design can withstand tests that shake it in all directions without breaking the seal.

The secure sealing method lets you carry it safely in backpacks, briefcases, and gym bags without worrying about spills. When it comes to business settings and outdoor activities where leak prevention is important, this insulated tumbler 40oz is perfect.

Innovative Press-Type Lid with Transparent AS Material and One-Touch Operation

Modern lid technology features a press-type opening device that lets you reach your drinks with just one touch. The clear AS (acrylonitrile styrene) lid material enables you to see how much liquid is in the container while remaining chemically and structurally resistant. 

The one-touch operation makes daily use easier, and the clear design makes it easy to see what kind of drink you're drinking and how much. As long as you use the AS material repeatedly, it will remain clear and impact-resistant. The tumbler's easy-to-use design makes it suitable for people of all ages and provides busy people with the convenience they need.

Wide 10cm Mouth Opening with Reusable PE Straw System

The large mouth (10 cm, or 3.9 inches) makes it easy to use, letting you add ice cubes or fruit and clean it thoroughly. The large opening makes it easy to fill from different water sources and gives full access to the inside for upkeep. The reusable PE (polyethylene) straw that comes with it gives you more options for drinking while also being better for the environment than single-use straws.

The shape of the reusable straw makes it easy to sip different kinds of drinks. The insulated tumbler 40oz features a dual-access design that makes it perfect for a range of drinking styles and adding ingredients to drinks.

Multi-Material Construction with SUS304 Steel, AS, PP, and Silicone Components

For optimal performance, advanced engineering uses several high-quality materials, including a SUS304 stainless steel body, an AS (acrylonitrile styrene) lid, PP (polypropylene) parts, and food-grade silicone gaskets.

The multi-material method ensures that each part performs its role effectively while maintaining the safety and integrity of the whole product. For insulation, the SUS304 steel provides the heat mass, and the PP parts make the structure lighter without lowering its strength. The food-grade rubber gaskets keep the lid flexible across a wide temperature range, and the AS cover lets you see what's inside.
