As fart as remember, ANA does not allow F passengers to take any non-consumables with them.

I flew on ANA First a few years ago, there was even no wash bag! I was handed a cheap sling bag or something and asked to take consumables from a basket.

The cheap bag as well as pyjamas were collected at the time of disembarking. I did not borrow, but they offered a woollen sweater, which had to be returned too.

I would never fly in ANA's F cabin, I can easily imagine ANA's First is so unpopular. So, if you want something "First", avoid ANA!
