20pk Super Strong Neodymium Magnets For Johnson Dog Tracking Collars & More

These little guys are super handy if you use a Johnson or similar dog tracking collar.

They're the shut-off magnets that activate the collar's switch.

This pack gives you 20 brand new, super strong neodymium magnets.

They're the 1x.25x.25 inch size, so they're small but incredibly powerful.

Even if you don't need them for a collar, rare earth magnets this strong are great for all sorts of projects—holding things on metal surfaces, picking up small parts, whatever.

They're unbranded but they do the job.

A good multipack to have around.
