Shivam is manufacturing hair straightening flat irons and supplying them to various beauty salons across the city. Over the last few months he observed that the sale of flat irons has decreased drastically. He tried to find out the reason.

So, he also started manufacturing ceramic irons based on new technology with added features like curling, crimping, etc.
