What are these new safety labels for?
Actually, these are the same labels that have always
appeared on our products! But, new guidelines have
prompted us to display any applicable safety labels
wherever products are sold. The goal is to keep you as
informed as possible about the products you purchase.

At Lakeshore, child safety is our first priority.
That's why our product testing standards exceed even
those required by U.S. law. But, if you have any ques-
tions about our products, we hope you won't hesitate
to e-mail Customer Service or call us toll-free at
(800) 428-4414, Mon.-Fri., 6:00 a.m.-6:00 p.m., PST.
Thank you!
