Rare earth square magnets / spacers.
Great for many DIY projects.
Playing with large bundles of these magnets can easily result in pinching your fingers with the force of pliers.
They can also shatter and spark with hard impacts, so safety glasses should be worn.
Definitely NOT suitable for children due to the serious health problems if swallowed.
Avoid using near to credit/debit card due to the magnetic strips and electronic equipment (e.g., pacemakers, mobiles, media devices, monitors, watches, TVs etc).
