It is quite easy to remove the magnets from the Magz. Just a squeeze with the cutters and then tapping the metal onto the magnet will remove them. Please note that this is a little wasteful - if you need to buy Magz or magnets for this project just buy the magnets. They should be fairly easy to find online. They must be 5mm diameter and you can stack two 3mm magnets (the size the Mags come with) or buy 6mm magnets for the best strength. I was given the Magz and used them for a little while before deciding that I would have more fun with the magnets. I used the steel balls on top of the soil in a potted plant to keep the cats from digging the dirt up. The plastic pieces were thrown out.
