I actually visited the Sakura Color Products Headquarters Factory in Osaka to produce a collaborative color pastel
A pattern of observing the manufacturing process is featured on MBS Mainichi Broadcasting System "Chichin Puipui"!
It will be broadcast that you actually participated in the final process of wrapping paper around the crepus.
Please take a look!
