If we wear a mask for too long, we will feel some pain in our ears because of the two straps of the mask. At this time, we can find something in our daily life, such as a plastic handle on a box of milk with two bayonets at both ends. We can hang the mask directly on these two plastic bayonets and then put it on, so that the rope of the mask does not need to be hung on the ear, so that even if one is worn, the ear can be relaxed. When we use homemade tools to tighten masks in daily life, we must pay attention to safety, especially things with sharp corners, and we must do a good job of protection.
