Let me start by saying that I am in no way affiliated with these guys, but I came across a post on another website and had to order a bunch. I'm jumping back in with both feet here.

They appear to be match stick sized sanding sticks with abrasive ends in varying grits. I plan to use them in typically obstinate wing roots and tight corners, but it seems to be a neat tool to complement sanding sticks and traditional sandpaper.

Their website is here:

I just wanted to show everyone something that impressed me.
