This is a shoulder bag from GABGAB. It's the original brand of the YouTuber Tanaka-ga. The synthetic leather is durable and highly resistant. Although it's a used item that I've been using, the zipper opens and closes without any problems, and there are no tears, so I think it can still be used for a long time.
