*by A***R on October 26, 2024*

These washers are great! Mind literally blown on how useful these are. One of my taillight assemblies had deteriorated around the holes where the screws go that hold it in place. This created an oversized hole for the screw. I didn't want to have to buy another assembly just because of this particular issue. Another issue was that the performed holes in the assembly were recessed. I found these washers and they did the trick. Saved me a lot of money 💰. They are flexible and came at a great value. I got a lot of washers in the box that I purchased for a decent price! I'm very satisfied with this product! 👍👍👍👍👍
