These amazing creations change from a humble, if fairly blocky, writing implement into a fully-fledged transformer. Made by Sentinel, there will be three different varieties: Optimus Prime, Black Optimus Prime and White Ultra Magnus.
The first one will be released in Japan in September, with the other two following in October. Prices start at $35 (£21) and you can preorder them here.
