GBP is 75% cotton 24% rag and 1% a special secret mix of very tiny particles of a mix of 3 or 4 metals, which is what machines pick up on, if the metal isn't present it will spit it out, but the paper will pass the pen which is all they use where i am, i am just waiting for the paper from China, they are cool they will sell you anything lol, i can do GBP 20's all day long but i'. Going to do my own.
