Dense cosmetics case (7)
I believe the answer is:
compact
This clue is a double definition.
'dense' is the first definition.
(similar in meaning)
'cosmetics case' is the second definition.
(I've seen this before)
(Other definitions for compact that I've seen before include "Agreement - brief" , "Small and neat - agreement" , "What comes initially with CD" , "Dense; agreement" , "Close - agreement - make-up case" .)
