Some people have wondered why some of the TF4 toys have hexagonal ports moulded into them... well now it looks like it was intentional, to allow people to use existing display stands... including one that Hasbro HK have produced as a freebie-with-purchase in Singapore.
It has the TF4 logo on it, and looks to be adjustable, and only requires a purchase of about AU$25 to get one for free.

Considering our ties with Hasbro HK, hopefully these show up in Australian ToysRUs stores soon as well.
