|This magnetic memo board is perfect for leaving notes on the fridge. The lenticular illusion will really make your messages stand out. A few years ago, this type of printing, which creates an amazing 3D effect, was very hard to get hold of. Now luckily, it is much more widely available. The edge of the memo pad appears to be higher than the central area, rather like looking into a swimming pool. As as you move your head left or right, you get a very effective 3D illusion. More Milk!!
