How do you use sunstick?

I enjoy using the sun stick because it's convenient.

Since I use this while going out, sometimes there is some foreign matter? Or should I call it that?

Should I call it dust? Hahaha, it sticks on really well. I've been shaving it off every time I use it, though.

As I was using it like that, I wondered if I was using it too wastefully, so I was wondering if others...

I wanted to ask because I'm curious how you use it haha

Still, I'm wondering if it's right to shave it off a little bit every time to use it cleanly haha.

Please give me some tips on how you all are using it~
