Review on 🛹 Mini Skater 16 PCS Black Generic ABEC 9 Longboard Bearings - High Precision 608 RS Skate Ball Bearings (Black) by Wayne Goff

I received these like most other recent reviews to use in 3D printed spinners for my kids (no I'm not a teacher). Eventually my 11 year old son would sell them to kids at school and even outside the house along with lemon juice and biscuits. good, but bad for fast spinning spinners. So I removed the caps and cleaned them and then relubricated them with Tri-Flow. I also had to scrape off the inner race on the caps as they were rubbing against the inner wall of the bearing. After that, these things spun like champions. The spacers in the bearings were different colors, some were yellow, white, black and clear. It didn't seem to affect their performance and none of the kids would see it. I've only seen myself disassembling them to clean them.
