Is coated paper hard? What kind of coated paper can be waterproof?
As the name card of 300g is to use the copperplate paper, plus double membrane, is that you can feel the hardness. Should not waterproof paper Oh (otherwise the printed fake money people not more cattle, as far as I know the money really short time immersed in the water without a little thing
Copper paper should be divided according to thickness, such as the common 128G, 157G, 200g, 25g0300g, the higher the number of grams, the thicker the thickness of the paper,
If it's fake, it won't work, so that's one of the biggest differences between real money and fake money
