ota0003 's Japan Review

I saw a friend using it and found it useful.
I also keep it in my darts case.

I think it can be used in many ways, depending on your ideas.

It is safe to have one.

I have one, but so far it hasn't been particularly useful...
I don't really know how to use it, but so far I haven't used it when the shaft won't come off or anything like that.
But if you can use it, I think it's small and just right.
