Gauge is fine but the product description and a photo says a metric set is included, NOT included. This is 60 Degree US Thread Angle from 4 to 84 Step Gauges 51pcs. and a triangular frame. The wording in the description shows that 52 pcs. Metric is included and "holes on each side" is a mistranslation indicating that the rectangular metric set (not included) has thumb cutouts to push any gauges out of the frame to sort them. The set of 51 triangular frames are humped to push the sensors out of the curved frame.
