Thank you for viewing my work. This is a navy blue arm band. The arm band simply attaches to your sleeve, allowing you to easily roll up your sleeves and put them back down. No more rolling and unrolling. Your shirt won't get as wrinkled. You won't have to worry about your sleeves falling down on flowy blouses, wide-sleeved sweaters, or pajamas. Arm bands are convenient for water work during the long-sleeve season, but they are also great when it's hot, when you're writing, or when you're doing crafts and 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 will make you look neat! I think even children who can't roll up their sleeves can do it with these. (Please consult before purchasing for size changes) They are essential for me and very helpful! For preventing water from running down your arms when washing your face, you can use them as stoppers by fastening them snugly around your arm (16 cm size is also available). How about a small gift for friends, mothers, grandmothers, or those who have helped you? The fabric is about 2.5 cm wide, about 20 cm long, and contains 1.5 cm wide elastic. 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
