Is there a difference between a cold extraction pipette cup and an ordinary pipette cup? I'm going to buy an accompanying water cup, and I'm a little embarrassed ~

Ordinary straw cups are generally used to drink warm water, while cold extraction straw cups are used to drink some cold drinks such as Leng Cha and cold extraction coffee, so more people use them in summer. For example, the cold suction tube cup I recently bought from Contigo ugly doll in the United States is a very beautiful and professional cold suction cup. No matter how it is shaken, it doesn't leak, and it is very small, so it is very convenient to put it in the bag.
