Small sewing case (4)
I believe the answer is:
etui
'small sewing case' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for etui that I've seen before include "Ornamental ladies' bag for small articles" , "Tiny ladies' bag" , "Small needle case e" , "Needlework case" , "Small case for small articles" .)
