Shimao 2

You’ve probably never seen the Shimao BrickHeadz before. He doesn’t come in a box, just a polybag, and he was only available at the Shanghai Shimao store opening in September 2018. It is believed that only 5,000 units of him were available, and while his only really notable aspect is that he has a printed brick to make him unique, he now sells for upwards of £100/$100 when he appears on eBay. Surprisingly, he doesn’t pop up very often on Bricklink.
