Walmart is recalling a card table and chair set after a person's finger was amputated.

The world's largest retailer said the Mainstays five-piece set can unexpectedly collapse.

It has resulted in nearly a dozen injuries, including one finger amputation and three fingertip amputations.

Walmart sold about 73,000 of the sets at its stores and online from May until November last year.

The sets were sold for about $50.

Consumers are advised to stop using the set and return it to Walmart for a full refund.
