Baby Lock Naki Star Serger Sewing Machine White

Thank you for looking!
This is a baby lock serger, model Nuki Boshi BL83WJ.

My grandmother used it, but due to declining eyesight, she stopped using it and passed it on to me.
I am not familiar with machinery and found it too difficult to use, so I am selling it.
According to my grandmother, there are no operational issues.

It is equipped with the Jet Air function, which makes threading easy.
There are some minor scratches and dirt from use, but overall there are no noticeable scratches or dirt.

This is a used item, so please purchase with your understanding.
We cannot accept returns or complaints after purchase.
