A rucksack that is easy to move even with large luggage and has both hands free. It's also ideal for travel, but if you carry it on your back, your luggage will disappear from your view, so you're worried about pickpocketing in unsafe places. Daiso's "Double Hook (S)" is useful in such cases.
This product is a light and durable carabiner-style key chain made of POM resin. It features a W hook that is easy to put on and take off.
It can be used as a key chain as usual, but it is excellent as a pickpocket prevention item for bags such as backpacks. If you close the zip and hook each knob on the hook, you will not be able to open it easily.

If you want to be on the safe side, it is better to carry it on your back or lock it in front of you, but that makes it difficult to move and opening and closing. It is the best item when you want to balance mobility and crime prevention, such as when walking in a place where there is not much traffic without stopping. Making it look like "it seems to be harder to work than others" is also effective enough to prevent pickpocketing.
