Stylus Pen for Fire Max 11 / Fire HD 10 with Battery Included

Purchased about 1.5 years ago for around 5,000 yen along with a FIRE HD10.
I bought it hoping my daughter would try digital drawing, but unfortunately, it wasn't quite what she expected. She ended up preferring to draw with her finger and it's been stored away since.
I'm now listing it for sale as part of a decluttering effort.
