Thank you for viewing my work. This is a navy blue arm band. The arm band simply holds up your sleeves, allowing you to easily roll them up and down. No more rolling and unrolling. Your shirt sleeves won't get as wrinkled. You can also keep the sleeves of flowy blouses, wide-sleeved sweaters, and pajamas from falling down. Arm bands are convenient for water work during the long-sleeved season, but they are also great when it's hot, when writing, or when doing crafts - anytime you want to roll up your sleeves. Recently, balloon sleeves with wide cuffs are cute, but they are easily wetted or soiled. Keep them up and clean with these! When your sleeves peek out from your jacket, keeping them up looks neat! I think even children who can't roll up their sleeves can use these. (Please consult before purchasing for size changes) This is a must-have item for me, and it's very useful! How about a small gift for friends, mothers, grandmothers, or anyone you're indebted to? The fabric is about 2.5 cm wide, about 20 cm long, and has 1.5 cm wide elastic inside. This is handmade by an amateur. If you have any concerns or are looking for perfection, please ask. Thank you very much m(__)m Arm band, sleeve holder
