A part of the review has been auto-translated.
The product packaging arrived almost painlessly. However, the package was strangely light, and when I opened it and checked the contents, the red ruler was not included. The problem was resolved through email exchange. It seems that there is a problem with the checking at the time of packaging. As a product, there are almost no scratches, and it is beautifully finished and wonderful. Just put the shoulder and ruler parts together and tighten the bolts, and the right angle comes out, which is great. On the ruler part, the scribe hole is almost perfect up to around 1M at the end, but the scale is slightly different from the scale on my ruler. The ruler part seems to have poor linearity on the upper side when the values can be read correctly. When aligned at the starting point, there is a slight gap between the rulers on the 1M side. The bottom side is almost straight and there is no gap in the middle.
used today for the first time, Really very useful and it is the square/line that I was looking for. I recommend it to those who work with wood
