The celebratory envelope from grandparents

In Japan, there is a tradition to hand money in a celebratory envelope at the wedding of a close friend or family member.
This envelope is decorated with artistic decoration because it is used for a expensive money gift.
This decoration is called "Mizhiki" in Japanese.

This was given to my son by his grandparents to celebrate his first birthday.
It is also used for celebrations other than weddings.
How about giving it as a gift to someone you love?
