Mr. Yeonjun, is this thing you put on your teeth called a tooth gem?

This is a concept photo for GGUM's solo activities...

It's been a long time since I've seen you again

Mr. Yeonjun, you used to put up a lot of those when you were active.

I suddenly can't remember the name

Grillz? Tooth gems?

Anyway, you wore the hip item well.
