Our magnets are made in Australia using top quality parts imported from the USA and archive quality paper from Austria. The magnets are medium strength. A single magnet and can comfortably hold two sheets of 80gsm paper. They are strong enough to hold random bits and bobs to the fridge but not so strong you need to use two hands to remove them! We think they are just right.
If you have a stainless steel fridge please be aware that the doors on some models are not very magnetic and can struggle to hold some magnets. The magnets they do hold may only be suitable for decorative use. The sides may be more magnetic than the front.
