Need Suggestions to Improve Sales After Restock

Hey everyone! I had a great sales boost in July, selling about 80-100 units in prime sale and improving my rank from 110k to 32-40k. Unfortunately, I went out of stock due to some delays (as Amazon lost my stock and my supplier got into an accident) and got back in October. Now, I’m seeing about one unit per day, and had a small spike on October 7th and 8th, but since then, only two orders. My sales rank is around 201k, and I’m getting clicks and impressions but no orders. Any advice on what I can tweak to boost sales would be greatly appreciated! I have got good feedback on my product so far.

the selling price is around 15.95$ which is lower than many competitors. Niche is lunch boxes. PPC spend is 10$ per day with one Exact KW Sponsored campaign and one category campaign.
