I heard your opinion well. I agree that giving and receiving eco-bags as gifts and people simply looking at and using designs. There are plenty of eco-bags and tumblers that people don't use in their homes. And it's also true that eco-bags and tumblers have to be used a lot to make an effect. But in the long run, I think it's better to keep trying to protect the environment. You may not be familiar with it yet, but if we keep informing and alerting the environment, people will move in the right direction.
