The changing colors are also proof of the passage of time.

The copper wedding anniversary is the seventh wedding anniversary.
The foundation for a marriage is established,
Everyday life becomes more "ourselves" little by little
This is the turning point where things start to change color.

Copper changes its appearance over time,
A material that grows in harmony with the user's lifestyle.
These changes are not a sign of deterioration, but rather a testament to the time that has passed.

Whenever you pick it up in your daily life,
It reminds me of the seven years I've spent together.
A quiet keepsake.
