Pens and needles (5)
I believe the answer is:
styli
'pens and needles' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for styli that I've seen before include "8 [NEEDLE]s" , "Ancient writing instruments" , "Writing, engraving, tools" , "writing implements" , "What engravers use" .)
