The Hobonichi Techo uses 12 soft colors across the book.
The TSUKI no IRO stationery series incorporates these colors into simple designs. This is a collaboration item with the stationery store Kakimori. This is a six-bottle set covering January through June or July through December, with inks blended to match the printed colors of the 12 months in the Hobonichi Techo book. Because the ink is water- resistant and resists fading from light, it is highly recommended for writing down important things like diaries that you want to preserve for a long time.
