On June 28th 2003, Pos Malaysia issued a new set of stamps, entitled "Islands and Beaches of Malaysia Series II", where Pulau Sipadan and Pulau Ligitan were introduced. the word Pulau means "island" in Malay for those who are unfamliar with the Malay language.
The 30 sen stamps depict the Ligitan island while the 50 sen stamps illustrate the Sipadan island. There is also a miniuature sheet issued and i will share it in another post later. Here I would only share with you the stamp sheets that hold 20 pieces of stamps of each island.
