Modified Pens and Materials for Pen Spinning

This is a retirement sale of items I created and purchased about 7 years ago.

These are the pens I used when practicing pen spinning, so there may be some minor scratches, although they are not very noticeable.
I found these while organizing, and I'm listing them in the hope that someone might want them rather than throwing them away.

Please understand that these are used items before purchasing.
I am not currently considering selling them individually.

I'm not sure about the market price, so I've listed them for 5000 yen for now, but I'm open to discussing the purchase price.
