I received this handmade item, and I used it for about a year before putting it away. The leather pattern and the rounded line at the bottom are lovely. The material is only described as genuine leather, and I'm assuming it's embossed cowhide, but it might be a different type of leather since it's thin. The thread color appears white in the natural light photos, but the yellowish color in the photos taken under incandescent lighting is closer to the actual color. There are scratches here and there from attaching it to a key case and from use. There are also scuff marks inside from metal. Flat measurements (not the size of the keys it fits): Width inside the stitching: top 27, bottom 31 Length: 26 mm approximately. (Please consider the thickness of your keys before purchasing.) I used it with a 23mm wide key, but the bottom width was too large, and it wobbled slightly. (I probably should have used double-sided tape.) I will also include a ball chain about 2mm thick (antique gold color). * This was used with a different key cover. It will be shipped via Yu-packet Post Mini.
