Hi, I just want to order the O/P miniature sheet but not the FDC or Setemku, is there a separate order form??
Currently Pos Malaysia is not offering the mint Overprint MS.
Not to worry. Actually plenty in the market. Maybe unsold Overprint MS might be sold in the future.
The market price is also not high as it was easily available during the mornings of the stamp exhibition.
