These are magnets specifically made to attach to cars, to be used by sign writers to hold the vinyl film on.
In the dog world we use these to hold sun shade or rain covers over our vehicle by putting magnets on each corner of the cover.
These magnets have a long “handle” so can also double as somewhere to hang your lead, toy etc.
