Breezliy 590Pcs 1-8mm Metric Precision 304 Stainless Steel Assorted Loose Bicycle Bearing Steel Ball Assortment Kit（12 Sizes）

Good price, quick delivery, and good quality

Case was broken, multiple bags were open including the one with the tiniest ball bearings.

came quickly. Was glad that I got the assortment of sizes. As it turned out I needed the next size than I thought. They were packaged neatly.

I rebuild a lot of older bikes and fix kids bikes. Invariably a ball bearing is missing from a headset race or a wheel hub. I can easily match them up with these free bearings and pop them into place. I’ve used these bearings for that purpose at least 5 times in the past few weeks. Going to need another box pretty soon. Hope that helps!

Bearings are slightly undersized so if you need exact sizes this might be an issue. Quality and service was excellent

Conceptually awesome idea, in reality the 6. And 6.5mm were slightly mixed making working with them much more of a pain than Id originally anticipated

Great product and reasonable price.

Just the thing for the hobbiest that gets into all kinds of projects..

I messed up spray pump, now I needed this to fix it.

Good variety. The different size ball bearings come in separate zip lock bags. The case arrived broke
