I read a blog about this soap and buy its smallest package about 15 rupees.It has a good fragrance and very good Crystal type structure and comes in medium blue colour . You feel cool for some minutes after the bath but not remains fir the long time.There is less chance of loose it due to its rectangular shape.But its weak point is that it is best for the summer but in the winters it dry the skin very much and you have to apply moisturizer.
Overall it is good product and you can buy it once.In india it is available in every second general store so easily available.
