Every fabric button is handmade, with love, by Rachel O. Earring measures approx .5 inch wide, and has a hypoallergenic, raw titanium post (not shiny). Posts are nickel-free and cadmium free. Fabric buttons are made of 100% cotton, hand stretched (by me) over an aluminum dome. Due to the handmade nature of your earrings, they will vary ever so slightly from the pair in the photo, but will be equally awesome. Earrings look their best when cared for properly. Please avoid getting them wet (remove before shower/swim), put on after applying makeup, and you will be able to enjoy them for a long time.
