Thank you for viewing. Regarding the SV12 I am selling, I mistakenly washed it with water, not knowing it was not washable. It worked fine before washing, but I can't confirm its operation now as I no longer have the main unit. Therefore, I am listing it as junk. Please consider purchasing only if you understand that it may not work. Although I washed it, there may still be dust, dirt, and scratches that I couldn't remove. Please understand that this is a junk item before purchasing. ※ No price reduction.
