Welcome, you are looking at a great accessory- this is the Nomad MN205 Guitar Surface and Hardware cleaning tool.
This tool was designed to keep your guitar in top performance condition.
Features a double sided microfiber cloth to keep you strings clean, and a soft brush for hardware.
I've personally found it's the perfect tool for something outside of guitars- Oreck Air Purifiers.
The microfiber end is the perfect thickness to go between the slats of the Truman Cell.
That makes this the perfect tool to stock up on.
Don't pass this by!
