My best suggestion is to take your own product photos so customers can't reverse search your product images. As an example, this set that you are charging $200 for can be found on Aliexpress for $38.50. Right now, you're essentially curating a collection of items that customers can easily find elsewhere for 1/4 of the price you're charging.
There is also no shipping information at all listed on your site which kills conversions. How long does an order take to get to me? Is 30 days a fair return timeframe for an item that might take 30 days to get to the customer? What's your value proposition? What's your story? Add this to your store.
Best of luck!
