The Open Easy Envelope is a very easy to use system. The Open Easy Envelope has a difference between the other inventions invented because it can be used on any type of Envelope, added just a new string feature to the envelope creating machine. A nylon string is attached about 0.5 mm higher then the fold line with a thin layer of glue. On each comer of the envelope are very small knots very close to the edge. As the String is pulled it opens the envelope easily or the string can be without a knot extending out of the envelope just a little bit. Also there will be a dotted line on the flap just about 2 mm below the fold horizontally. As the dotted lines are ripped just a little the string is left in the hands. The reason the string is put 0.5 mm higher then the fold line is because when the envelope is folded the string does not get in the way. The same processes can be used on the bottom and right sides of the envelope.
