Close-packed cosmetics case (7)
I believe the answer is:
compact
This clue is a double definition.
'close-packed' 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 "What comes initially with CD" , "Condense" , "Small and neat - agreement" , "woman's case" , "Dense; powder case" .)
