Review: These are a great set, the tray they come in is even high quality! I've used them a lot in my job as a heavy equipment mechanic the fit is tight and has not loosened a bit yet. The chrome version most people use will fracture and shell out over time these have lasted through what would have been 2 sets of a cheaper brand and still look basically new. the sizes included cover about any job and the engraved writing is super easy to read.
Review: Thanks for perfect product
