These are Arcon knobs, which were used on Sadowsky NYC guitars, etc. I bought them in a boxed set, so they are original, one-owner items. Please check the photos for signs of use, small scratches, and paint剥がれ (peeling). One of them is unused as it was attached to a Stratocaster, but please be aware that they have been handled by someone. I have tried to describe the noticeable scratches in the photos, but since I am a layman, the current condition takes precedence. Please feel free to ask any questions or request additional photos. Set of 4 black control knobs with a stripe pattern. - Color: Black - Shape: Round - Design: Stripe pattern - Material: Plastic - Quantity: Set of 4 Thank you for looking.
