While it might be refreshing to drink a refreshing cold beverage delivered by an equally cold metal straw, it’s much less enjoyable when that straw becomes a stabby thing that can cut your mouth.

That’s why Starbucks is recalling more than 2.5 million stainless steel straws in the U.S. (as well as 301,000 products in Canada): the company is providing new warnings for the products, after it received three reports of mouth lacerations in young children who were drinking with the straws, the Consumer Product Safety Commission says.

The reusable stainless steel Cold-to-Go food grade drinking straws that are being recalled feature a ridge at the bottom to keep them attached to the lid, and come in two sizes. They were packaged and sold in sets of three, and also come with two sizes of stainless steel beverage cups: Grande 16-ounce cups and Venti 24-ounce cups.

The straws were sold exclusively at Starbucks locations nationwide and online at starbucks.com from June 2012 through June 2016 for about $6 per set of three, while the beverage cups with straws sold for between $11 and $30.

If you’ve got one of these products at home, don’t let your children use or handle them. More questions? Contact Starbucks at 800-782-7282 from 3 a.m. to Midnight PT daily or online at http://www.starbucks.com and click on “stainless steel straw warnings” for more information.
