These are leather flower charms in a variety of colors. A set of 2 pieces each of 20 different colors of leather: blue, purple, black, white, green, yellow, orange, red, and pink. There is also some hard, enamel leather included. Recommended for leather craft parts. There are 40 pieces in total, 2 of each of the 20 colors. We have gathered colorful leather pieces. We hope you enjoy them as materials for your leathercraft projects. The size is 14mm x 14mm. There is a hole of about 1mm in the center. How about using them for earrings, ear studs, charms, or other accessories? The thickness of the leather varies from 1mm to 2mm. If you are using rivets to attach them, we recommend using very small rivets. The length of the rivet legs depends on the thickness of what you are attaching them to, but 6mm or longer should work. As these are natural materials, there may be some scratches or minor imperfections. We try our best to cut from the cleanest parts of the leather, including the back, but there may be some fuzziness. Please understand. The color may differ slightly from the actual product due to the way the photos are taken. We will discount the shipping cost if you purchase other items together. Thank you for looking.
