Airdog Dust Collection Filter Brush - Brand New, Unused

Thank you for looking.

This is a cleaning brush specifically for Airdog's dust collection filters.

It was opened for photography but is brand new and unused.
I thought I had lost the one I already owned and bought a replacement, but then I found the original right away. I would be happy if someone could use this.
It was purchased at the end of December.

Thank you for your consideration.
