This is a bag by GUIDI. This bag is made of soft horsehide leather, and it will become more comfortable as you use it more and more. The shoulder strap is tied in one knot inside the bag, and the length can be adjusted by changing the position of the knot. The bag is unlined, and the inside is divided into two sections by a partition, allowing you to put things separately. It is a good size, not too big, and can be worn with a variety of styles.
