### ⭐⭐⭐⭐⭐ 







  
  
    Perfect little wheels for making a wire straightener tool, nice bearings!
  

*by M***E on Reviewed in the United States 🇺🇸 on February 8, 2023*

Love them!  Right size, price, and smooth ball bearings. I'm going to make a wire straightener tool for DIY and jewelry making.  Youtube has lots of demos.  No more at the mercy of silly nylon pliers that come undone, and hard on the hands.  This will work for miles of wires of all sizes.  Thank you!

### ⭐⭐⭐⭐⭐ 







  
  
    Smooth and good quality.
  

*by D***E on Reviewed in the United States 🇺🇸 on November 23, 2020*

Not much to say other than they are smooth and well made. They should be able to smoothly roll even with a decent amount of weight.
