They may look cute, but these children’s folding hair brushes are actually chock-full o’ lead — with 25 times the amount allowed by United States law, according to federal officials.

Nearly 800 of them were seized in Baltimore, Maryland, this week by Customs and Border Protection officers, who had sent them in for chemical testing upon their arrival from China on May 22.

The brushes — which are adorned with pictures of unicorns. cupcakes and flowers — had been marked as “hats, gloves, hookah.”

The Consumer Product Safety Commission ran a product analysis on them last month and discovered “dangerous” lead levels exceeding 2,500 parts per million. The normal levels should be no more than 100 parts per million, according to officials.

“As any parent knows, young children have a tendency of putting their toys and accessories in their mouths, and so some children would likely get very ill from these hair brushes that contained a dangerously excessive amount of lead had Customs and Border Protection not seized them,” said Casey Durst, CBP’s Director of the Baltimore Field Office, in a statement Friday.

“Intercepting dangerous consumer products at our Ports of Entry is a CBP trade enforcement priority,” the official added, “and we remain committed to working with CBSP and other partners to ensure the health and safety of American consumers.”
