A German discounter currently has these little First Aid kits for 4€ once again, I think it's an annual thing.
This time I got myself one to put on my belt, and with that I should now always have some basic First Aid stuff with me, even in the rare cases when I can't bring my backpack. 😊
Of course the content isn't comparable to my usual DIN kits, but in most cases where I don't have my backpack with me, I don't need anything more than band-aids anyway.
