Wrigley product (3)
I believe the answer is:
gum
'wrigley product' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for gum that I've seen before include "Part of mouth; a tree" , "Gingeva is its technical name" , "Leaving body" , "Adhesive for chewing" , "Sticky plant substance" .)
