316 stainless steel intelligent temperature coffee cup

This thermos flask is made of inner 316 stainless steel and outer 304 stainless steel， The inner layer of 316 stainless steel has higher corrosion resistance and is suitable for storing and transporting acidic or alkaline liquids, so the inner layer 316 can better prevent corrosion when the liquid comes into contact with the cup wall, ensuring the quality and safety of the liquid. The outer layer of 304 stainless steel has the same strength, making the thermos cup more durable and scratch-resistant, while also having good wear resistance and not easy to damage. Stainless steel materials usually do not release harmful substances, which means you can use this thermos with peace of mind without worrying about harmful substances seeping into your food.
