    box broke, all parts messed
  

*by D***L on Reviewed in the United States on March 16, 2023*

well, I can't give 5 starts because the container didn't survive the shipping. all parts were shuffled.other than that everything is fine

### ⭐⭐⭐⭐⭐ 







  
  
    Need a Good Selection of Small Size Metrics?
  

*by R***M on Reviewed in the United States on August 22, 2022*

Use the smaller sized metrics - 3, 4, 5, etc. - this box has all you'll need with washers and nuts to complete the package.

### ⭐⭐⭐⭐ 







  
  
    Good quality but poorly packaged
  

*by D***R on Reviewed in the United States on September 23, 2022*

The screws seem to be a good quality, I haven't seen any unthreaded nuts or bolts and a neodymium magnet test shows they're only slightly magnetic, which is indicative of stainless steel. However, the nuts were scattered all over the box so I had to take time with a set of tweezers to re-sort them. Annoying, but not much else.
