Dustboxes serve as a way to send items to and from the 3 main groups in Mary Skelter: Finale.
They start to appear once you enter Eiserne and are crucial for getting through the dungeons, as you will need to send the other teams keys and other items to progress. It is also mandatory for completing commissions. Sometimes you will need to send an item to Toh's group in order for Thumbelina to shrink said item, to then send it onward again.
Its icon is that of a garbage bin and the blood maidens will respond to your usage of the dustbox, treating it as a simple way to dispose of items, or just outright confusion as to why you're using it.
