Price is per magnet.
These are the same magnets used in our Glasses. They are 20mm x 5mm. Made from the highest grade neodymium and coated in zinc to prevent oxidation/rust, these magnets are strong, capable of holding 14 lbs of tensional load when stuck together.
Please take care not to let these magnets come together unimpeded. As with all strong magnets, this may cause them to chip or shatter. Use your hands to bring them close, or separate them with something like a spare scrap of minky.
