Now you can prepare delicious and aromatic drinks right in the thermos mug of the world-famous brand THERMOS - the NS-403 model has a compartment for tea leaves, which easily attaches to the bottom of the lid. Create your own recipes, fill this compartment with any ingredients, and their prolonged interaction with hot water inside the thermos mug will make your drink especially rich and appetizing. The compartment has a lid and a filter with a micro mesh, so tea particles will not get into the thermos mug and will not interfere with drinking. When it is necessary to change the tea leaves or rinse the thermos mug, the tea compartment can be easily removed, disassembled, and easily reattached to the lid. Intensive brewing of the drink and keeping it hot for at least 12 hours are ensured by deep vacuum insulation, design features, and premium materials. The body and inner flask are made of food-grade 18/8 AISI 304 stainless steel, which is corrosion-resistant, does not react with drinks, and preserves their original taste. Special metal processing technology provides perfectly smooth walls, preventing residue buildup and absorption of aromas. The lid is made of modern Eastman Tritan® material, which combines the advantages of glass and food-grade plastic. This material is highly heat-resistant, durable, BPA-free, and does not absorb or release any odors even at high temperatures. The thermos mug's tightness is ensured by a food-grade silicone gasket and seal, which are heat-resistant and durable. All materials used are safe, environmentally friendly, and recyclable. The thermos mug fully complies with the International quality standard EN12546-1:2000. In the hot season, the thermos mug can also be used to store cold vitamin drinks - thanks to the vacuum insulation, they will stay fresh for up to 24 hours, and for a longer period, you can add ice cubes. Special comfort when using the thermos mug is provided by the ergonomic shape and original design of the lid. You can drink from the mug even on the go without removing the lid - just fold back the locking ring and press the button, the top lid instantly flips open, stays fixed in the open position, and does not tip over during drinking. The lid has two openings - for drinking and air flow, ensuring a smooth liquid flow. The locking ring prevents accidental opening, so you can safely carry the thermos mug in a bag or backpack. Compact size allows you to place the thermos mug in a car cup holder or bicycle holder. The sleek modern design, long service life, and impeccable characteristics make the NS-403 thermos mug not only a stylish but also a useful functional purchase for daily use.
