‼️ This is a single-layer cap. ‼️ Made of silk, so it's gentle on the skin and hair. ‼️ Can be used for funerals, Obon, etc. ‼️ For outings during hospitalization or treatment... ‼️ Doctors in general can wear it without it being considered rude, as it's not a hat. ‼️ Tie the ribbon at the back to fit your head circumference, and sew it to the elastic part. This will secure the back.
