Instant purchase available, no price negotiations. Functionality has been confirmed to work correctly in Street Fighter 6 on PC, PS4, and PS5. The 8 main buttons have been replaced with new Qanba Gravity KS silent buttons (color: Clear Violet Black) for this listing (only function checked). These are high-end silent buttons highly regarded by pro gamers and advanced players. The lever has not been replaced and is the original Sanwa Denshi lever. There are no scratches on the black acrylic top panel. Regarding other parts, there are few signs of use overall, and I think it's clean, but please ask if there's anything you can't see in the photos. I have performed a simple cleaning with alcohol for this listing, but I have not disassembled and cleaned it, so if you are concerned about dirt that cannot be removed from small grooves, please clean it after receiving the product. The sticker on the Qanba Gravity KS button caps is new and has not been peeled off, so please peel it off after receiving the product. There are no accessories other than the arcade stick body shown in the photos. 【Notes】 ※ I do not provide support or answer questions about how to use the product.
