Recommendation for the brush received when buying blush

This is a brush that came as part of a set when I bought blush at Peach C.

The bristles are short and very soft, so I found it convenient to use haha.

To be honest, I'm terrible at makeup, so I don't really know which brushes are good.
I've seen a lot of things here and there where people said it's better to use tools than my hands, so I'm just using them.

The brush is short and small, so it is very convenient to carry around when traveling.
