I'm holding a photo review event for Park Sung-jin's official merchandise.

Park Sung-jin Official Goods SECRET KEYCAP KEYRING

We're holding a photo review event!

It's about posting a photo of your own custom keycap keyring~ 

No matter what you look like in everyday life, it's OKAY! Seongjin will select 20 people through a lottery

They give you a hand-drawn keycap and keyring as a gift.
