Monzzi Double-Walled Insulated Coffee Thermos

Our double-walled thermos keeps hot beverages for up to 8 hours and cold for up to 6 hours! The advanced thermal insulation creates a vacuum chamber that prevents heat transfer. For maximum efficiency, we recommend preheating or precooling the thermos with water before use. We tested it in the lab and confirmed that after 6 hours, hot beverages still maintain a temperature above 65°C, ideal for consumption. Performance may vary slightly depending on the ambient temperature, but thermal retention is consistently superior.

We recommend hand washing to preserve the integrity of the thermal insulation and the wooden handle. The high temperature and harsh detergents in the dishwasher can compromise the thermal seal over time. For cleaning, use warm water with mild detergent and a soft-bristled brush to reach all corners. The wide mouth makes this task much easier. For the wooden handle, avoid prolonged immersion and dry well after washing. Occasionally, you can apply mineral oil to the wood to maintain its natural appearance.

Yes! The handle is made of high-quality natural wood, treated with protective varnish that ensures durability and moisture resistance. The wood used is specifically selected for its strength and natural beauty. With proper care (avoiding prolonged immersion and drying after washing), the handle will maintain its appearance and functionality for many years. The attachment is robust and supports the weight of the full thermos without issues. If necessary, the varnish can be periodically renewed to maintain the original finish. It is normal for natural wood to develop a patina over time, adding rustic charm to the product.

Absolutely suitable! The internal glass is completely inert and does not react with acidic substances, preserving the flavor and properties of the beverages. Unlike some metallic materials that can alter the taste, our high-quality glass maintains the original purity of juices, sodas, wines, or any acidic drink. You can safely use it for lemonades, berry juices, coffee with lemon, or other citrus beverages. The material does not absorb odors or flavors, allowing you to alternate between different types of drinks without cross-contamination. After using it with acidic beverages, just wash it normally.

The 1000ml capacity is ideal for individual use throughout an entire day or for sharing in small groups! It equates to approximately 6-8 small cups of coffee or 4-5 large mugs. It is perfect for office use, eliminating the need for multiple trips to the coffee maker. For families, it meets consumption well during meals or snacks. The size is optimized to be portable without being bulky - it fits well on countertops and is easy to transport. For commercial use or larger events, we recommend having more than one unit. The compact dimensions (13.5 x 22.5cm) take up little space while offering generous capacity.

Maintenance is simple and ensures a long lifespan! For daily cleaning, rinse with warm water after use and wash with mild detergent using a soft sponge. The wide mouth facilitates access to all areas. For deep cleaning weekly, use baking soda with warm water, let it sit for 15 minutes, and rinse well. For removing odors or stains, diluted white vinegar is effective. Always dry completely before storing to avoid residual moisture. The wooden handle should be cleaned with a slightly damp cloth and dried immediately. Avoid abrasive products or steel wool that may scratch the glass.

Absolutely versatile! Besides coffee, it is excellent for all types of teas, hot chocolate, cold drinks like juices, flavored waters, iced teas, and even liquid soups. The inert glass does not alter flavors, allowing use with any type of beverage. Many customers use it for detox waters, protein drinks, iced mate, and even wines that need to maintain temperature. For carbonated beverages, we do not recommend long periods due to internal pressure. The insulation works to keep drinks both hot and cold, making it useful year-round. It is a complete solution for hydration and culinary pleasure.
