My flat, black matte finish stud earrings are hand formed from polymer clay (I don't use molds or forms). I sand them using 3 different grits of sandpaper, followed by buffing them with cloth, to produce a beautiful matte finish. They are strongly affixed to hypoallergenic titanium posts (nickel-free and lead-free). You will receive one pair of earrings in your choice of diameter: 5mm (3/16 in), 7mm (1/4 in), or 9mm (5/16 in) (see last picture). Usually I have plenty made, so they ship within a day or 2. My fun, colorful, stud earrings are very versatile. They fit right in with casual and more formal looks. Your order arrives in a small, cardboard jewelry box. If you need more than one jewelry box for gifting please send me a convo and I'll make a custom listing for you to account for increased shipping charges. Also, if you'd like to include a note for gift giving, please let me know in the "notes to seller" upon checkout. As with all handmade items, handle with care. Please don't immerse earrings in water (remove them before swimming or bathing). Due to the handmade nature of these earrings, they may vary slightly from the ones pictured. Also, keep in mind monitor settings can be different from computer to computer so the color might vary slightly from what is pictured.
