Sanshin - Metal Tuning Pegs (Karakui) - Rocket Type (3 pieces) - Used - Won't break, won't loosen

Special tuning pegs for Sanshin - Rocket type, set of 3, used.
Sujigane tuning pegs from Sanshin Kobo Jinan.
These are unbreakable tuning pegs.
Removed from a Sanshin I owned.
The original price for a set of 3 was ¥17,600.
The product description states:
- Unbreakable
- Won't loosen
- Improves sound
etc.
If you are interested, please search for them online.

Please read the following important notes carefully.
Unlike regular tuning pegs, Sujigane tuning pegs have a metal tip (see photo 4), which requires drilling holes. Please only purchase if you are willing to drill holes in your own Sanshin. (Quoted from Sanshin Kobo Jinan's website)
They generally recommend sending your Sanshin to Sanshin Kobo Jinan to have the tuning peg holes (pilot holes) processed.
This means you will need to process the smaller of the pilot holes to match the metal tip of the Sujigane tuning pegs. This does not mean you need to shave down the metal part.
- I did find that these tuning pegs do not loosen and are unbreakable.
* The holes for the strings on the metal part are present, and they are in the same position on all 3 pegs. The string holes on regular tuning pegs are in different positions on each of the 3 pegs.
Please be aware of this point as well.

I hesitated to list these, but I hope someone who can do the necessary modifications and is interested will consider them.
Please be very careful, as modifications are required.
We cannot be held responsible if you are unable to install them, so please understand this in advance.
Thank you.
