Thank you for viewing my work. This is a white arm band, slightly larger than usual, suitable for men as well. It's 25 centimeters long. Please check the circumference of your bare arm at the point where you want to secure it. You can easily roll up your sleeves by attaching the arm band to the cuff. Since you don't have to roll them up, your shirt won't get wrinkled. Keep your shirt from peeking out from your blazer for a neat look! It also solves the stress of sleeves falling down on silky blouses, sweaters, and pajamas! For those who wear long sleeves in summer to prevent sunburn or from the over-air conditioning, Recently, wide sleeves, long sleeves, and yukata are cute but easily get dirty and wet. Some people are buying larger sizes to raise them up to their upper arms. They are popular because they are not readily available in stores. Fabric width is about 2.5 cm, 1.5 cm wide flat elastic, 25 cm long. Please check the size of your bare arm at the point where you want to secure it. If you would like a size change, please comment before purchasing, and I will change it if I have one ready-made. This is a handmade item by an amateur. If you have any concerns, are looking for perfection, or would like a size change, please ask. I have many other arm bands on sale. Please take a look at my shop if you like ＼(_ _) Thank you.
