17 Things You Should Never Buy Used

 Helmets

By purchasing a bicycle or motorcycle helmet at a thrift store, you could be unintentionally putting your safety at risk. You have no idea who owned it before you, how old it is, or why they got rid of it. According to the Bike Helmet Safety Institute (BHSI), your helmet should be replaced after hitting your head in any crash. They recommend never buying a used helmet because it may have been involved in an accident. Instead, purchase a new helmet and feel confident that your head is protected.
