Grivel Crampons G12 EVO

I bought these intending to switch from semi-one-touch to one-touch crampons, but they are incompatible with my Montbell Alpine Cruiser 3000 boots, so I'm selling them. ↓↓

I only tried them on at home.
When I removed the front metal fitting on the right crampon to adjust it, I scratched it because the fitting was too stiff. ↓↓
I can't return them on Amazon, so I'm selling them.

Please see images 2 and 3 for the scratches.

I purchased them for ¥29,000, so I cannot lower the price any further.
I have already significantly reduced the price.
Thank you for your understanding. m(_ _)m
