A. This is a unique camping cup made of 304 stainless steel, featuring good durability and safety. B. It has an outdoor - style design with cartoon patterns, which is both fashionable and full of fun, meeting diverse aesthetic needs. In terms of manufacturing process, it uses a powder - coating process, and the curled part that comes into contact with the mouth is not coated, ensuring safety and health.

Whether you are working in the office and need to replenish water at any time, enjoying a cozy time at home, relaxing in places such as bars, restaurants, lounges, cafes, and teahouses, participating in outdoor activities like camping, picnics, and barbecues, or even in the car, it can be your good companion. D. The single - cup capacity is 300 milliliters, which is of a proper size to meet daily drinking water needs.
