One Drop 10-ball bearing: Never used, so it’s probably still a bit responsive and extremely quiet.
2x YoYoFactory SPEC (not SPEC-X) bearings: Rarely used, dead responsive and still spin quiet smooth.
Selling all 3 bearings together for $17 shipped. Sorry, not separating them 
Shipping to USA/Canada only.
No trades.
ps. I have 50+ feedbacks in my YYN profile some time ago
