An estimated 580,000 glass coffee mugs have reportedly been recalled across the US following reports of burn and cut injuries due to the cups breaking while filled with hot liquids.

AP reports that a Thursday notice from the U.S. Consumer Product Safety Commission, the now-recalled JoyJolt-branded “Declan Single Wall Glass Coffee Mugs” can crack or break when filled with hot liquids.

It’s understood that there have been 103 incidents of these glasses breaking at the base according to the CPSC — resulting in 56 injuries.

Among the figures of injured, there are 35 reports of burns across the body from spilled hot liquid and 21 cuts, with seven requiring medical attention like surgery and stitches, as per ABC.

Consumers in possession of these recalled mugs are urged to immediately stop using them, and contact MM Products for a full refund.

The company noted that voluntary recall was issued because consumer safety “is our top priority” — later adding that it appreciates impacted customers’ understanding and cooperation.
