What is the required product name format. I want to sell a pack of 200g Arnott's Tim Tam's original flavour?

We request all sellers to to use the product name form brand, product name, size and then the number of units in the listing. e.g. Arnott's Tim Tams Original 200g x 1. If the pack size is "x 1" can then the "x 1" is not required.
