Headbands are 2 layers of 100% cotton fabric, with buttons for the masks’ elastic ear loops. These mask headbands are great for alleviating pressure from the ears while wearing a mask, especially for day-long wearers. The buttons placed just above the ears to latch your mask elastic around while still covering the nose, mouth, and any facial hair wearers may have. There are round, heart, and flower shaped buttons available that will match the colors in the headband. Please make a note if you care for one type of button in particular. Designed and made in the USA, materials sourced by primarily small local businesses.
