To get on to shelves, Chinese-made items must overcome shortfall in electricity and workers, as well as shipping crisis
At a toy factory in south-east China, boxes of plastic dart guns are stacked across the floor. Sometimes, so many packages pile up that they stretch into the production area, slowing the work of making more toys.
What to do with all the blaster guns, which have been sold to retailers in the UK but cannot find room on ships to get them there, is a problem for Nick Mowbray, the co-founder of Zuru Toys. The company expects to generate about $1.1bn (£815m) in revenue this year thanks to surging demand for products such as 5 Surprise Mini Brands, Rainbocorns and X-Shot blasters.
