One would think that one can not go far wrong with this kind products - far from it. The "magnetic" pen holder does not even carry his own weight. If he is then also fitted with 2 pins can not even stop the lower end strip of the board it. In addition, the felt dissolves at one end as of yet. the plastic caps of the magnets are quite large, the magnets themselves unfortunately not so. Therefore, although they cover a lot of holding but not good. Saves you the trouble
