    I bought this magnet for magnet therapy and it works great! You still have to be careful for your client to not touch it.. because pull force is very strong. I would recommend this one versers quarter inch one for therapy magnet.

  • very strong

    I was wondering , since it's thin type magnet, how the strength is, but it's very strong. Nice for magnet therapy.
