Glad to see them when they arrived. However, I was disappointed after CAREFULLY installing them to install tires. I've been careful not to damage them in any way. I was surprised to see that even after I used the wrench by hand, they seemed to never end. It doesn't look like the material is BLACK, it looks like they are PAINTED BLACK. Still good value for money. It will be interesting to see how they hold up in winter and on salty roads.
