The traditional sticky notes are generally made by paper, and very wasteful. For this problem, Sun Jin has a concept. And notes by intelligent base board composition, the principle is similar to give children a magnet drawing board, available when using the magnetic pen drives the memo board inside of magnetic particles arranged in a word, and through the intelligent base to set the alarm clock, when time is up, the memo board will glow. Memo board can repeat use when it back into intelligent base demagnetization.
