Hope you are doing good!
As you searched this product and want to go with this product so first, you can start it with Amazon with small stock to check the response. If you feel you are getting good sales then you can start with huge stock.
For snapdeal and Flipkart I want to suggest you first check sales response on Amazon. If you feel its selling good then you can obviously start selling it on these two marketplaces.
For further queries, you can revert back to us.
Thanks & Regards,
