[I]I bought it from Agha's Super Store in Karachi. And this is pressurised canned air spray is the only effective tool for cleaning anything where even service wala's pressure air or an air blower fails to work for you. This product even works in popping out minor dents and dings from your car. Epic stuff. I use it for computers, electronics even my Glock.
I tried to find it in Metro Islamabad, CSD Rawalpindi, Green Valley Bahria Islamabad, Shaheen and other numerous stores but couldn't. So finally I asked a friend at Karachi to send me from there but it cannot be sent via courier. Now they will arrive via good old coach service. But it's expensive though (Rs.585/-). By the way it could be acquired cheaply from Sitara Market Hayatabad (Karkhano). [/I]
