The product I like is the 5 mil (.005 in/.127 mm) Medium Pewter 9.25" X 12" (234.95mm X 304.8mm) for $8.55.
The plain and colored 3 mil (.003 in/.076 mm) Light Aluminum films are also useful, the colors are available in 60" rolls.
The company I linked, Dick Blick, does ship internationally:

All of the foils are dead-soft and easily worked.

The product is also sold in art and 'craft' supply stores in the US, Michael's and CraftMart I know for sure carry the product.
Art and craft stores can be a great source for materials.
