haa0005 's Japan Review

It is easy to use because it is a card type and can be used in any place.
However, you need to be careful how to use it at first.

It's convenient because you can do so many things with this one card.
It's a card-type card, so it's not bulky and easy to store, so it's very good!
However, it is difficult to understand how to use it, so I give it a 4.

It comes in handy when I'm worried about tips stuck in the dartboard.
I use metal shafts, so it is essential.
