The U.S. Consumer Products Safety Commission (CPSC) has issued an official recall for children’s insulated water bottles manufactured in China and distributed exclusively by L.L.Bean. The water bottles were imported by Spokane, WA-based GSI Outdoors, Inc. The solder at the exterior base of the bottle contains elevated levels of lead, though no incidences of lead poisoning have yet been reported.

The recall includes kids’ 13.5-oz. water bottles with printed graphics in five different prints: Dino Bones, Flower Power, Orange Grid Camo, Purple Tie-Dye Butterfly and Robo Shark. A sticker with the item identification number “297684,” as well as the numbers “PO#844” and “BB2D2-LLB-R45-0413,” is located on the bottom of the bottle.

“Consumers should immediately stop using the recalled water bottles and contact L.L.Bean for a full refund,” said the CPSC in an official statement.

About 6,700 bottles were sold by L.L.Bean for about $20 each through its retail stores, catalog and website between July 2015 and May 2016. While GSI Outdoors, Inc. is not an ASI-listed supplier, a search of ESP for “kids’ water bottle” turned up 632 items from 105 suppliers.
