Creative: This buckle comes with this back bag got a built-in Whistle / Aerophone

As a backbag for daily use, this bag got all the functions that I need! but this is not what I need to note here.

it is the buckle. Yes, the buckle, it is a buckle for many other buckles.

It is also a whistle, not that loud, but very creative. You may not bring all the things with you when you are on-the-go. In case you don't have one, this may help.

Yes, it is a little bit that it is not that loud that you can only say it is better than with none!
