Recently, the weather has been rainy and the temperature has been high. It's hot and humid. It's too uncomfortable. I make herbal tea for a living every day. Is there a better cold extraction cup?

It's raining at a high temperature, and I feel that the sky is full of boiling water. This day is so hard that I can't live without herbal tea every day. I usually use Contigo cold extraction pipette cups. This herbal tea is good, and it can keep the refreshing taste of herbal tea. It tastes fresh and fruity, and it is leak-proof. I can carry it with me in my bag.
