Is it correct to use mixins in this way?

Question

Sass

Salute to all!
I wondered if it was correct to use mixins in this way (without arguments)?

@mixin flex {
    display: flex;
    justify-content: space-between;
}
@mixin center {
    display: flex;
    justify-content: center;
    align-items: center;
}
@mixin column {
    display: flex;
    flex-direction: column;
}
