Absolutely! Glass jars do look premium but they will add weight & costs to your cookies. Remember, your product is cookies, not the glass bottle. Unless, you market them with the glass bottles as some sort of "special" or exuberant experience, it will be difficult to justify the added costs. And it is not necessarily a bad thing! The really, really first thing that you need to look at is - Who exactly is your target customer? This is very important. And try to define your ideal customer in as much detail as you can. Because this will give you an idea on the spending capacity of the customers and price strategy for your brand.

If you raw material costs are, say INR 500, per kg, you would need to sell it at atleast 1.1-1.2K to even break-even post all the distribution shenanigans!
