This is Kai-Bureu, always with you haha

There is a replacement rubber at the bottom so you can change it right away.

It's also an advantage...

I hear a lot of people use Shiseido these days, but honestly, this suits me best, so I'm still using it.

I feel like I'm the only one living a bit in the past... lol

I tend to buy a new one only after I've used up all the replacement rubbers... but for some reason, the new ones feel like they slide on better, so I end up buying fresh ones periodically haha.
