I've set the size to M, which is what I usually wear, as I'm not sure how to express it. I don't have specialized knowledge, so I may not be able to answer detailed questions, but I will do my best to respond within my knowledge, such as adding photos. Also, please understand that there may be some errors due to amateur measurements. Because of indoor photography, 100% color reproduction is difficult, and the color may appear different depending on your browser environment. The color and shade are largely based on personal subjectivity, so I would appreciate it if only those who understand the risk of judging based on images online without seeing the actual item would consider purchasing. I try to ship as quickly as possible, but it may take some time for shipping and arrival. Please understand this in advance. I check the items beforehand, but there may be some oversight of minor stains, fraying, small holes, etc. Please refrain from purchasing if you are looking for perfection. The condition of the item is based on personal subjectivity. This is a used item, so please refrain from purchasing if you are nervous about it. I am very sorry, but I will give priority to those who purchase first. I am not responsible for any loss or damage during shipping. Returns will be determined through the administration. If you have any concerns or questions, please feel free to consult with me in advance.
