Tokyo circuit diagram circuit board art bookmark is made of an industrial printed circuit board. 

The materials, processes, and production of the substrate are identical to the original substrate.

Artisan removes 0.15 mm copper foil from the edge of the substrate to prevent damage to books, notebooks, and hands. The board art bookmark is made of a 0.3mm thick base material, but the total thickness is 0.45mm when combined with gold plating or silk text on both sides.

Design (drawing): Uses a dedicated CAD for substrates that are not soft and we draw individual lines by mouse. The thin line is finely designed with 0.1mm wiring pattern. Narita Airport mark is applied at Narita Airport (NRT) and the Hanada Airport (HND), and the shipment mark is placed in Tokyo Bay. The train station name is represented in 3 silks (ex: TKY Tokyo).

Pink are inks that act as an insulating film to protect circuit patterns. 

Designed and manufactured in Japan.

Parts are not implemented.

The bookmark is packaged in a transparent bag. (Not gift boxed)
