OM Tuning Fork Set (5 pieces)
- Frequency: 136.10 Hz x 2
- Frequency: 544.40 Hz
- Frequency: 272.20 Hz
- Frequency: 68.05 Hz

The 544.40 Hz and 272.20 Hz tuning forks produce a beautiful sound when struck with a mallet, but also when gently tapped against each other.
Purchased from Sun&moon several years ago. Used a few times, but I own many tuning forks and don't get much use out of these, so I'm selling them.
The covers are in three parts. There are some areas that have become slightly scuffed and white. Please see the 7th photo.
