This is a Cath Kidston shoulder bag. I bought it as a mother's bag and used it for about a year, but there is some discoloration and slight tearing on the inside due to aging. It has a large capacity and can hold a lot of documents. It's also sturdy, so I think it's safe to put in precision equipment like a PC. The width is approximately 35cm, measured by an amateur. It also comes with a shoulder pad, making it easy to carry even heavy items, so it's useful for various purposes such as commuting, going to school, or as a mother's bag. If you only need it for a temporary period during childcare, it's more than sufficient, so I recommend it to those who are about to start raising children.
