I'm glad to read your opinion :)
In my opinion, disposable products are not the answer, but using tumblers isn't the best way to protect the environment. According to a study, tumblers are effect when we use them at least 30 times. Of course, the number isn't too much. But I think the problem is 'season-limited'. People tend to buy tumblers that are limited even they don't need to. I am never saying don't use tumblers. Tumblers are effect when we use them for a long time. Otherwise, they are just waste. So the important thing is not whether we should use the tumbler, but make a good decision depending on the situation. Thanks for your reading!
