Super-strong cube magnets, from Swiss Trendform. The magnetic cubes are silver-grey in colour and have sides measuring 8 mm. The cubes look the same on all sides and will attach regardless of which side you place against your magnetic board.
The magnetic strength of the cubes is extra high, which means they can also be used on surfaces with slightly weaker magnetic properties, such as a glass magnetic board or a surface painted with magnetic paint. On a sheet metal surface, these magnets attach very strongly and can be a little difficult to remove! Of course, it will be easier if you have attached a stack of paper under the small cube!
Please note that strong magnets can be dangerous for children and pets.
