These are the joy cons from older bundles that are being re-added in the 2023 MAR10 Day Bundle. This is a more accessible way to get the joy cons without dealing with the bundle.
Mileage may vary but I have bought 3-4 consoles and 2 sets of joy cons from Nintendo’s refurbished store and all have been perfect
