On 11 December 2019, there was a surprise announcement of the Ejen Ali The Movie Personalised Stamp (Setem Ku) Folder Set being sold in Sunway Pyramid in LG2, Concourse.
The folder set was sold at RM 35.00 which consists of a folder, a Personalised Stamp (Setem Ku) sheet, an empty envelope and a postcard. There is no special cancellation.
It was supposed to be on sale on http://www.eziemall.com but as at the time of writing, I could not locate the product.
