Used Best Brass e-Sax Tenor

This is a used e-Sax for tenor saxophone from BEST BRASS.
I received it about 15 years ago, but it has been stored unused for nearly 10 years.
I tested its operation for this listing, and it worked without any issues.
I home-cleaned the felt, but there are still some key oil stains remaining. (I don't believe there are any noticeable odors.)
Additionally, the top packing (felt around the neck insertion area) and the band packing (felt around the hand insertion hole) were damaged, so I removed and disposed of them.
Parts can be purchased from the following page, so please refer to it:

If you wish, I can also include a guitar stand that can hold the e-Sax upright, free of charge.

As this is a precision instrument, it will be carefully packaged for shipping. However, please understand the risk of damage during transit before purchasing.
Thank you for your consideration.
