Solid cosmetics case (7)
I believe the answer is:
compact
I believe this is a double definition.
'solid' is the first definition.
(thesaurus)
'cosmetics case' is the second definition.
(I've seen this before)
(Other definitions for compact that I've seen before include "Compress; agreement" , "An official agreement" , "What comes initially with CD" , "Tightly grouped" , "Make denser, agreement" .)
