It is good to use an empty oil pen bottle when applying concealer.

It's a hassle to use a separate brush when applying concealer, isn't it?

If I go on a trip, I have to pack as many as two things~~

In that case, try putting it in an empty oil pen bottle and using it!!

If you search for "empty cuticle oil pen," you'll find an empty bottle with a brush attached; it's originally used for cuticle care.

If you mix concealer and your used foundation in there instead of oil and store it...

It's super easy to use lololol
