How much does it cost to buy a thermos bottle for a hotel?

As far as I know, the price of thermos bottles on the market is generally about 150 yuan each, which is relatively expensive, but the quality is not bad! Nanlong thermos bottles can be divided into three categories: ① Slim mouth type. Usually also called a thermos. The mouth has a small diameter and good heat preservation performance. It is mainly used to hold boiling water, decoction and hot Chinese medicine juice, hot drinks and cold drinks, etc. ②Large mouth shape. Usually also called ice bottle.

It is mainly used to hold ice cubes, sorbets, cold drinks with containers, icing medicines, liquid gases, anti-fermentation substances, etc. It can also hold hot food, hot drinks with containers, etc. ③Cup shape. Usually also called a thermos cup. The mouth has a large diameter and a small capacity.
