The "WB Nice Water Bottle" is a generic type of water bottle, often a glass bottle, with a capacity of 400ml. The "WB Nice" or "Nice" brand doesn't appear to be a major, internationally recognized brand, but rather a name used for various products sold by different manufacturers and traders, particularly those based in China and other Asian markets.

Here's a breakdown of what "WB Nice Water Bottle China 400ml" generally refers to:

Origin: The bottles are typically manufactured in China. They are often sold through online marketplaces like Alibaba, Made-in-China.com, and other local e-commerce sites.

Design: They are usually made of glass, sometimes with a double-walled design for insulation. They may have a plastic or silicone outer casing or sleeve for protection and a better grip. They often come with a screw-on cap, and some might have a loop or handle for easy carrying. The design is often described as "simple," "sleek," or "fashionable."

Materials: Common materials include:

Glass: The primary material for the bottle itself, chosen for its non-toxic and eco-friendly properties.

PP (Polypropylene) and Silicone: Used for the cap, outer sleeve, and other components. These are food-grade and BPA-free plastics.

Stainless Steel: Some versions might be made of stainless steel with a vacuum flask design to keep liquids hot or cold.

Capacity: As the name specifies, the capacity is 400ml, which is a relatively small size, making it suitable for carrying in bags for short trips, school, or the office.

Usage: They are marketed for daily use for drinking water, juice, milk, and other beverages. The bottles are often promoted for their reusability and contribution to reducing plastic waste.
