Bought these because I work with Klein tools and for the typical “where did you get those?” Or basically an excuse to talk about how cool I am for owning these. Highly recommend.

These are really cool
Size: One Size
What a cool set of grill tools! They say USA made, but the parts are from all over, one says made in China and the other says made in Taiwan, lol. Doesn’t matter, they are real Klein tools, well made stuff.
