Purchased about two weeks ago. Free size. Please refer to the photos (back of the box). I am selling it because it is difficult for me to use. Used only once. Washed, dried, and stored. The smell of rubber still remains. The box has been opened, so it is open. Therefore, I am selling it at a low price. There are no smokers. To prevent trouble, I have not created a dedicated page. I will prioritize the person who buys it first, even if there are comments. Thank you. (*^^)
