Pop Mart, the maker of the hugely popular Labubu dolls, says its sales have surged after the launch of mini versions of the monster-themed toys in August.

The Chinese firm says its global revenue for the three months to the end of September jumped by about 250% compared to a year earlier.

Sales outside of China helped drive the increase with revenue in America up by more than 1,200%, while in Europe they rose by over 700%.

The figures build on a recent streak of strong sales for Pop Mart. Its shares gained more than 5.5% in Hong Kong on Thursday, giving it a stock market value of about $45.5bn (£34bn).

Pop Mart is best known for selling toys in "blind boxes" - a type of packaging that conceals its contents until it is opened. The marketing method has been criticised for encouraging gambling-like behaviour and compulsive buying.
