"Quick to wrap and easy to open" There are 3 tricks for the Japanese diagonal wrapping to be successful; the "Zen" / "Han" flips, the paper size and the box position.

It took many months for me to find out the 3 tricks. Until then, I failed many times in front of my costumers (very shameful!). I compiled the techniques in 5 minutes, and hope everyone can master the Japanese diagonal wrapping today!
