This marking tool worked wonders for me! Through trial and error I found that it was the perfect solution to marking parts in my automotive repair shop. It's easy to use and makes the job a breeze .The marker produces clear and visible marks, which made my work more efficient and error-free. However, the only downside is that the marker's tip can wear out quickly, so make sure to use it with care. Overall, a great addition to any mechanic's toolkit..
