When magnets are anyway super. This strength in the small size is really impressive. Several pieces of paper or paper in a clear plastic folder are retained without any problems. The size is not much visible even on densely printed paper and the magnets do not fall far on as much as larger normal magnets.
As with the other reviewers already repeatedly noticed: the small size has its drawbacks. To replace a single die with your fingers is a challenge. It is also without cancel fingernails, but you felt as though you with an excavator lifting a glass of water (somebody remembers Wetten dass ...?). Successive enforce is a perfectly reasonable alternative. When the magnets often have to be moved, a tower of two or three dice is much better to take hold. If a magnet permanently in one place, ranging from a single well.
In my case, the magnets, of which I will soon have the 100-he wants to order package arrive, on the refrigerator and the whiteboard is used. 100 pieces may sound a bit exaggerated, but the dice can be great for larger cubes or towers together and hold each other very well. And already a 2x2x2 cube "consumed" 8 this small cube and really good grasp is for me a height of three dice.
