Total length: 260mm With millimeter and inch scales I am retiring after 40 years as a mechanic and am now decluttering my tools, which have become almost a hobby. I purchased this as a tool for business trips, but I never used it and kept it in my toolbox. It works well. There are some scratches and dirt from storage. Please refrain from purchasing if you are sensitive to these issues. Please read my profile carefully and understand everything. I am selling with no claims and no returns. Please consider this. *Please negotiate discounts through the "Price Negotiation" feature. I will respond whether I can accommodate your request or not.
