A touch-up stick used to cover blemishes

It's a disposable makeup touch-up stick sold at Daiso for 1,000 won. There are as many as 100 pieces in the pack!

I was watching YouTube shorts when a beauty YouTuber recommended this as a concealer brush. The tip is really small, so it's great for dabbing concealer onto blemishes or spots to cover them. If you use tip concealers but struggle to cover small spots because the tip is too big, I recommend giving this a try.

Besides being used as a concealer, it is said to be good for applying something to very small areas or for correcting nail art, as indicated on the packaging.
