Firm cosmetics case (7)
I believe the answer is:
compact
I believe this is a double definition.
'firm' 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 "An official agreement" , "The powder-box is closely packed" , "Concise" , "Mutual agreement" , "Make denser, agreement" .)
