Idea was somewhere in my mind as nobody had ever thought of this and I used to get enquiries for showcases. But as a business practic, I do not sell anything which is not portable. Almost all the display stands or banner stands do not require any tools to assemble or use.
Truth is ideas may lie dormant as seeds till somebody comes along and prods you to stir in action. One of old client mentioned lack of any portable product in this segment.
As the design was already in my mind, it just required, assembly and execution and finally the product is ready for marketing.
