These armbands are perfect for the long-sleeved season! (^^) They're great for cleaning or doing water work, when your sleeves keep falling down even after you roll them up, causing frustration ↷↷. They eliminate the hassle of constantly re-rolling your sleeves. Two thin pieces of elastic are used, so they stretch softly. The opening for the elastic isn't sewn shut, so you can adjust the length or replace the elastic. 【Size】4 cm x 9 cm Please understand that there may be slight variations. 【Material】100% Cotton They will be delivered with simple wrapping, so they can also be used as gifts. I make them carefully, but they are handmade by an amateur. Please understand that there may be some imperfections in the stitching, etc., before purchasing.
