No article before lipstick?
I took an English listening test. The dialogues from the audio goes:
W: Dad, this Sunday is Mom’s birthday.
M : I know. Did you find a good present for her?
W: Yes, I bought nice lipstick. I’m sure she’ll like it.
I think that an article "a" must be inserted before 'nice lipstick', but the speaker did not say it, right?
Even the script had no "a". I'm confused. Is it really correct without "a"? Since it's an official test, I doubt they didn't have English native speakers proofread it. Confirm please.
