Fayez Shweikh, one of Gaza's up-and-coming businessmen, shakes his head as he considers his mixed fortunes.
In the past year, he had significantly increased his household income by investing in a black-market, "tunnel" economy, which relied on smuggled goods siphoned through underground passages between Egypt and Gaza.
Israel has always maintained that the tunnels were used to smuggle arms and explosives, but Shweikh says food, gasoline, and household treats – chocolate, in particular - formed the basis of his trade.
"I purchase goods from the chocolate company directly in Egypt; from such companies as Galaxy, from Ferrero or the Kinder Company. I buy, I transfer money and they send me the goods, by way of normal businessmen … tunnel businessmen."
