The magnets are extraordinarily strong- I use high grade Neodymium Rare Earth Magnets. These amazing little magnets will not lose any appreciable strength during your lifetime. They are hands down, the strongest and most amazing magnets you can buy, far superior to the black ceramic magnets others use.
If you're looking for push pins for your cork board, these little guys are great for hanging up photos, artwork and notes.
These marble magnets are handmade by me so each is unique and because they are actual marbles each will differ slightly in size and shape. Pattern placement will also vary.
Be sure to convo me if you'd like these as push pins instead of magnets or if you'd like a larger set!
