designer's own words:
We defined the word anticipation as a flower. We wonder how beautiful it become from a bud. It is kind of process of waiting, which means anticipation. Also, we make our anticipation bigger day by day until the day come. The process of blooming flower resembles the situation when our anticipation gets bigger. And what we found from people around us is that everyone has his or her d-days in a year.
Whether it is birthday or exam, They are all waiting for the day. So we made D-day flower for everyone who has time for waiting.
It is a form of a bud before you set your d-days. After done with your setting,it counts the remain days through the calculating system in the pot. A leaf starts to spread out before your first d-day. And at your first d-day, It spread out perfect with light from the stem. The flower blooms perfectly with light when your last d-day ends.
