(Non-Genuine) XBOX Series X Controller LB RB Replacement Parts x3

Replacement parts for the LB/RB buttons of XBOX Series X(S) controllers (x3).
These are compatible parts imported from overseas, not genuine products.

I am using another unit that I purchased at the same time, and while I personally didn't notice much difference in operation feel, I have the impression that the durability is slightly inferior to genuine products.
(I have replaced them several times, and I estimate the durability to be about 2/3 of genuine products.)

I have some spares, so I can accommodate requests for 4 or more units.
If you wish to purchase more, please leave a comment.

Shipping will be via Nekoposu.
These are unused items, but there may be initial scratches. Please refrain from purchasing if you are looking for a perfect item.
