PoIC : Pile of Index Cards

I use blue pigment ink just because it's comfortable for me. The color can be change as your favorite.

I use pigment ink because,

1. high visibility
   
2. un-erasability
   
3. low pressure for writing
   

The cards are keep in a box called "Dock". The high visibility is important when flipping cards in the Dock. And this analog system is basically permanent system. A copy of our life. If is easy to erase, it means we lost our record. The third factor is important because we write a lot of cards. Physical effort must be reduced to keep writing.

I use Pilot's Pigment Drawing Pen 0.5 mm (Top of the picture above) for long time. It is enough strong pen-head, reasonable, and water resistant.
