It is the first time that Malaysia has issued International Stamps that is for mailing for overseas and will be sold to the public without Government Service Tax. It cannot be used for domestic mailing. Other stamps used for domestic mailing will be subject to Government Service Tax as of October 1, 2016.
I created these First Day Covers at Sungai Petanin Post Office in Kedah and George Town General Post Office in Penang. As there was a public holiday, these stamps went on sale on Monday October 3, 2016 in Kedah and on Tuesday October 4, 2016 in Penang.
