Good Seasons Italian Dressing Mix, 2 Packages with Cruet, 1.4 Oz. Net (Premium pack)

What’s the difference between the basic pack and the premium pack?

Is cruet glass or plastic?

I ordered this a few months ago. didn’t open it until recently and discovered the cap was missing. quite disappointed. can i get the cap?

Can I buy more cruet tops? I keep losing them.
