I use a double-sided brush as a hidden gem.

I'm using a double-sided brush, and I find it really convenient.

On one side, apply cosmetics evenly to tidy up.

And on the other side, you can comb it to finish it off.

You can do all of this at once with a single product.

It would definitely be a good idea to have at least one of these products, wouldn't it?

Give it a try; you won't regret it.
