The COLUMBIA sapphire needle SJN-71 is a high-quality cartridge for record players. - Model: SJN-71 - Brand: COLUMBIA - Color: White/Black/Yellow - Features: Sapphire needle Although it is unused, it has been stored for nearly 30 years, so it may have deteriorated. When I touched the protective sponge for the photos, it left marks, indicating deterioration. I think the needle itself is probably usable, but I can't test it, so please understand that it is non-refundable and non-returnable. Thank you for looking.
