## Questions & Answers

**Q: can i use these as brass knuckles instead?**
A: No . They wouldn't hurt anyone . I returned the one I had didn't do what they are intended for

**Q: Is this supposed to be some kind of a joke, like a gag gift?**
A: We sent it back. Maybe it is a gag gift because it certainly didn’t work for a normal human hand.

**Q: Two questions:  do they come with nunchucks and also, can they be used with toes, instead of fingers?**
A: This device is for strengthening your finger reach for a guitar or other string instrument.  It would not be suitable for anything else.

**Q: Will this device also work for banjo??**
A: This device is the greatest answer to helping anyone who plays a stringed instrument. I am a 'boomer and suffer from the ravages of arthritis. I routinely use my finger stretching tool to exercise the fingers of  my fretting hand. I expand the the individual 'guides' to achieve maximum stretch. As I do this , I flex my fingers at the first joint and in so doing mimic the the finger positioning to properly  create chords on the neck of the instrument. I now have greater reach, less stiffness and increased flexibility. Even if I didn't play an instrument this is a fantastic therapeutic device to stave off the limitations imposed by arthritis.
