hi, anyone know where to buy depron from cochin.. . i was using a foam named cooling foam which doesnt have enough stiffness........

Why don't you buy it online? It is available on ebay.

You have to hunt down places that do advertising. Visit a few, and you will know.

Any exhibitions happening will lead you to them, just ask the companies which advertising company prepared the hoardings / signboards (although coro is also widely used for the same).

thank u both of u
