These genuine leather flower parts are mainly in black. Some are made of glossy, hard enamel leather, while others are made of matte, thin leather. Some leathers have embossed patterns, and a variety of leathers are included. You can enjoy them as materials for leathercraft. Size: 14mm x 14mm There is a hole of about 2mm in the center. The leather thickness varies from 0.9mm to 2.2mm. When attaching with rivets, we recommend the extra-small rivet head 5mm. The length of the legs depends on the thickness of the item to be attached, but 6mm or longer can be used. As they are natural materials, there may be some scratches and minor imperfections. We try our best to cut from the clean parts of the back, but there may be some fuzziness. Please understand that the actual color may differ slightly from the photos. If you wish to purchase them with other sets, please let us know in the comments. Thank you for viewing.
