Hello, Rdbi 

I would use metafields. Metafields are a flexible way for add additional information about a Shopify resource, such as a product. Read these articles first link  second link and watch some video about metafileds on Shopify.

I hope that my answer helps you to resolve the issue. If you need a more detailed explanation or further help - just contact me.
