Vaccum portable cup flask 3litres color vary

When looking for a vacuum portable cup flask with a 3-liter capacity and varying colors, consider the following points:

1. **Capacity**: Ensure the flask can hold 3 liters of liquid. This is relatively large for a personal portable flask, so check for products designed for high capacity.

2. **Insulation**: Look for double-walled vacuum insulation to keep beverages hot or cold for extended periods.

3. **Material**: Stainless steel is commonly used for its durability and insulation properties.

4. **Portability**: Even though it’s 3 liters, it should have a handle or strap for easy carrying.

5. **Colors**: Verify that the product comes in multiple color options to suit your preference.

Here are some specific models and brands to consider:

1. **Thermos King 3-Liter Flask**: Known for its high-quality insulation and durability, available in various colors.

2. **Stanley Classic Legendary Bottle 2.5L**: Slightly smaller, but high-quality with various color options.

3. **Zojirushi Stainless Steel Vacuum Carafe**: Typically around 2 liters, but known for excellent insulation and comes in different colors.

When purchasing, check online retailers like Amazon, eBay, or specialty kitchenware stores to compare prices, colors, and reviews.
