Starting a stall business requires careful planning, a strong understanding of one's market and a commitment to providing exceptional customer service.

It is perhaps for this reason that a mechanical engineering student at Masinde Muliro University of Science and Technology (MMUST) has invented a unique collapsable structure that vendors can use to display their groceries.

According to Kaguru Njoroge Muchina, the pioneer of the Flexi stalls, they are simply made of wood for support and partitioning as well as metal for grills that hold the goods. "Compared to other grocery kiosks, flexi stalls are more hygienic, presentable structures and are portable, thus efficient and reliable for mobile vendors," he observes.

The pricing of the stalls ranges from Sh1500 to Sh3500 for the small and big ones, respectively.
