Magnets are all arrived were attached directly to our table already deduct the first time I had with one of the magnets only the plastic piece in his hand the magnet got stuck.
The magnets can be no liability will be used for a maximum of 1-2 pages 90g paper otherwise is given.
Price performance: For 3 I would say you can not expect more, but inferior to 6.
Appearance: very reminiscent of the magnets used in the classroom.
General: I would grab here more likely to be more expensive, since one is not really happy with this.
