Product Safety Warning Details

Description:

The U.S. Consumer Product Safety Commission (CPSC) is warning consumers to stop using Ocensmice magnetic building stick and steel ball sets immediately. The magnetic building sets violate the mandatory standard for toys because the small sticks contain stronger than permitted magnets that fit within CPSC’s small parts cylinder, posing a risk of serious injury or death if ingested by children. When high-powered magnets are swallowed, the ingested magnets can attract each other, or other metal objects, and become lodged in the digestive system. This can result in perforations, twisting, and/or blockage of the intestines, blood poisoning and death. 

CPSC urges consumers to stop using the magnetic building sticks and steel ball sets immediately and dispose of them. Do not sell or give away these hazardous magnetic toy sets.  

CPSC issued a Notice of Violation to the seller Shenzhen Shibeilongxiangkejiyouxiangongs doing business as Ocensmice, of China. CPSC has requested that Ocensmice recall the magnetic building sets and provide a remedy to consumers, but Ocensmice has not agreed to an acceptable recall.    

The toy sets consist of magnetic building sticks in light purple, dark pink, blue, orange, red, yellow, dark purple, dark green, light pink and light green. The sets include steel balls and a grey drawstring storage pouch. The sets are sold in a box with the words “3D Building Blocks” on the front.
