The pot-in-pot preservation/cooling system was invented mainly to help rural farmers preserve their farm products. The product was persistently refined for two years between 1995 and 1997. Using personal savings, Abba tapped into the large, unemployed, local workforce, and produced the first set of pots numbering 12,000, which he distributed to farming households freely. This was done to promote the appreciation of the product as well as stimulate local demand for it. In 2000, he began full commercial production of the pots using local pot makers with each participant making between 15 and 20 pots a day. The pots sold for between US$2 (N300) for the smaller pot-in-pot and US$4 (N600) for the bigger version. As of 2005, the inventor had delivered over 90,000 pots and production has continued to increase.
