'toiletries' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe there's a link between them I don't understand?

'lists featuring no flipping' is the wordplay.
'lists' becomes 'rolls' (roll is a kind of list**).
'featuring' indicates putting letters inside.
'flipping' says the letters should be written in reverse.
