Ryeo Shampoo Scalp Massager

This is the scalp massager that used to come with Ryeo shampoo.

Opinions are divided on whether using a scalp massager is good or bad, but for now, I'm using it just fine.
I wondered if it might hurt since the end is pointy.
Maybe it's because it's soft
I switched because it was better than the one I used to use.
Because I lost it early on
I bought shampoo again because of this even though I wouldn't use it.
I haven't lost it since then and have been using it well for several years.
It was good that water didn't get inside.
Moisture is building up inside after using it for a long time.
I looked it up while I was writing this, but if I can't use it anymore, I'll have to switch to something else.
