Drawer containing a corny novel? (6)
I believe the answer is:
crayon
'drawer' is the definition.
(something which draws)
'containing a corny novel?' is the wordplay.
'containing' indicates putting letters inside.
'novel?' is an anagram indicator (letters in a new or novel order).
'corny' is an anagram of 'cryon'.
'a' inserted within 'cryon' is 'CRAYON'.
(Other definitions for crayon that I've seen before include "Stick of coloured wax for drawing (6)" , "Producer of sketch" , "Wax pen" , "Wax colouring stick" , "Source of colour" .)
