Review on 🛹 Experience Superior Performance with Mini Skater 16 PCS Silver ABEC Precision Skate Ball Bearings for Longboards (16 Hulled) by Christian Young

The bearings I received are not suitable for making spinners. Inside they are filled with grease, which can be useful for other purposes, but this prevents them from spinning freely and not completing even one turn when clicked. Also, they felt a bit sticky due to the fat. I tried cleaning the grease with acetone but those bearings didn't have a removable cover so I couldn't clean the grease. I assume they will work for motors or other purposes, but not for the purpose I intended.
