Nintendo's official Joy-Cons, confirmed to be working after maintenance. The sticks have been replaced with new 【4th generation】 ones. There are no button issues, and there are no problems with attaching and detaching them from the main unit. Immediate purchase is OK. 200 yen OFF for bulk purchases! Can also be used with Switch 2 if connected wirelessly. The surface has discolored to a yellow-orange color, though the cause is unknown, possibly due to sun exposure. There is no smell, so it's not nicotine stains. Other than that, it's in beautiful condition with no scratches or signs of use. There may be oversights such as scratches, so please check the images as it may be difficult to see. Please refrain from purchasing if you are looking for a perfect product, as this is a used item. I will check again for any defects before shipping. When disassembled, I have performed simple cleaning, wiped the surface with a disinfectant sheet, and polished it with a melamine sponge. When the product arrives, please reset the controller settings, such as updating the controller and calibrating the sticks, from your Switch console. In the unlikely event of any defects, please contact me before you rate the product. I will not be able to respond after the rating is received, so please understand. Feel free to comment if you have any questions. For price reductions, please use the price reduction request function.
