David Union Ergonomic Pen Sander 400

Finally, a sanding tool that actually fits into those tight corners and slots I always struggle with. The narrow design makes detail work on my craft projects so much easier than using folded sandpaper.

I was skeptical at first, but this pen sander handles those tight recessed spots my regular tools can't reach, and the ergonomic grip actually makes long sessions painless. It's definitely made my craft work more convenient.
