Height: Approximately 18cm Width: Approximately 23cm No gusset Although it is new and unused, please understand that it has been stored by a private individual before purchasing. (Stored in a bag as shown in the fourth photo) There is one divider like a pocket inside. It's a large pouch, so I think it can be used in various ways, such as a bag-in-bag or a pen case.
