These are leather flower charms in a variety of colors. This set includes both colorful and chic options. Some colors have two pieces each, but light green and pink have only one each. There are some glossy, hard enamel leathers, as well as some matte, thinner leathers. I think you'll enjoy them as materials for leathercraft. Size: 14mm x 14mm There is a hole of about 2mm in the center. How about using them for earrings, ear cuffs, charms, or other accessories? The leather thickness varies from 1mm to 2mm. When attaching with rivets, we recommend using extra-small rivets (head 5mm). The length of the legs depends on the thickness of what you are attaching, but 6mm or longer can be used. As they are natural materials, there may be some scratches or minor imperfections. We try our best to cut from the cleanest parts of the back, but there may be some fraying. Please understand. The actual colors may differ slightly from the photos. If you would like to purchase them with other sets, please let us know in the comments. Thank you for looking.
