Review on 🛹 693ZZ R 830ZZ 619 Miniature Skateboard by Mike Wallace

I recently bought these to replace some of the bearings in my UK Arms M249 gearbox on the cheap. I was very happy with them as they are true to size and all spin freely with no issues after using them for an hour. I also like how they are sealed on both sides compared to the previous ones I've had which were prone to dirt, metal shavings etc. Exactly what I needed at a great price.
