### ⭐⭐⭐⭐ Good ball-bearings in useful sizes
*by N***S on 12 April 2023*

Ball-bearings were good value and they included a 3.5mm one, which was the one I needed at the moment. They were slightly dull, suggesting that the finish may not be as durable as others but they are certainly good value for money (£7.99) and hopefully will last as long as they need to. Four stars because of the finish.
