Did you visit one of the M&M’s World retail stores in NYC, Las Vegas, Orlando, or London earlier this year? Did you see some adorable pint and shot glasses featuring the anthropomorphic treats? Well, you might want to stop using them, as those cute candy illustrations may contain high levels of lead and cadmium.

The FDA has announced a recall of six different glasses — three pints and three shot glasses — featuring three different designs that were exclusively sold at the M&M’s World stores previously mentioned.

As you can see from the above photo, the three designs are:

*The Red M&M’S character with the words “Hard on the outside, soft on the inside;”

*The Blue M&M’S character and the words “Who’s your candy?;”

*The Green M&M’S character and the words “Eye candy.”

The recall only affects the 1,202 pint glasses and 6,335 shot glasses sold between the dates of January 8, 2014 and April 16, 2014.

The affected glasses can be identified by the SKU# printed on the sticker affixed to the bottom of each glass.

SHOT GLASS RED: SKU# 835986
SHOT GLASS BLUE: SKU# 835989
SHOT GLASS GREEN: SKU# 835990
PINT GLASS GREEN: SKU# 835993
PINT GLASS RED: SKU# 835991
PINT GLASS BLUE: SKU# 835992

Consumers who purchased the recalled shot and pint glasses can return them for a full refund to any of the four M&M’s World stores or contact the company at 1-800-848-3606
