They come in a nice little plastic case with plastic dividers between each magnet. These are strong magnets. They are difficult to parse even when delimiters separate them. I ordered these to use in combination with sous vide plastic cooking bags. I figured they would do good weights on the outside of each plastic bag. They are too small to be very effective. They make decent fridge magnets, but again, they're strong and very difficult to remove from the fridge door. If you are looking for strong, powerful, yet small magnets, this is a great option. .
