any usages for phantom mask?

Sometimes I got a phantom mask from Hunter ranking reward box(1st) but I don't know any useful usages of this.

This is not fusionable and not have any rune holes.

Are there any special or useful usages of this? (such as a material for making or upgrading something?)

If not, is it ok to throw it away?

it's just for looks. you can throw it away. why not keep just 1 for memory/costume?

Thank you for answering my question.

Thanks to you, I can throw them away without any doubt.

As you know, that's not fusionable and have no rune holes.

If it has no real usefulness, there's no reason to keep and use it. (I'm not a fancy nor showy player.)

Besides, I receive it almost everyday - there are few players here... -

and one mask occupies one slot.

I think it's useless.. It has just value of 10 rupee.

Anyway, thank you.
