Please read my profile before purchasing. Purchased from 3COINS. It's a shoulder bag that can fit a smartphone. 3 pockets 1 inner pocket Size: Height: Approximately 18 cm Width: Approximately 13 cm Never used. Please refrain from purchasing if you are concerned about minor details. There are two instances of negative feedback: One is that the seller didn't respond for several days, and after contacting the administration, I received negative feedback after the transaction was completed. The other is that I overlooked the fact that some of the contents of a book were missing due to my mistake. I will strive to prevent such incidents from happening again in the future.
