This is the ELECOM "Active Touch Pen Premium" compatible with the Surface series.
It is a model that supports the Microsoft Pen Protocol 2.0.

Although the package was opened after purchase, I did not own a compatible Surface device, so the pen has never actually been used for writing.
For this listing, I have only verified that it charges correctly.

As I do not have a compatible device, I have not been able to test functions such as writing or button operations.

The original USB micro-B cable is missing, so I am including a substitute USB micro-B cable (the one used to verify charging).

The package contents include the pen itself, a substitute USB micro-B charging cable, the user guide, and the outer box.
The outer box shows signs of tearing and wear. Although the item is unused, it has been stored at home for a long period, so please expect minor scuffs or imperfections.

It is unused, but its operation on a compatible device has not been verified.

The outer box is torn and worn; please check the photos for the condition.

I appreciate your understanding regarding these points.
