Star Diamond kits come in many sizes and the most affordable is a small box that will barely make a dent in your wallet. PHP 35.00 for the smallest kit gives you a “minifig” and a vehicle / accessory. Pictured here are the crane kit and the SCUBA diver with DPV kit. Compared to the real LEGO, the main difference lies in the minifig copies because they require more assembly versus the real deal which I honestly don’t mind doing.
Where can you find this? I found an accessible stall at the NBC Tent Weekend Bazaar. The unmarked stall is found towards the end of the tent hall and you can find several other brands from China as well as the real stuff.
