The price is high, but thick and clip functions are good (so it's easy to use)
It is differentiated from cheap. Because it looks nice, you can use it feeling well for customer service with documents in between. (Especially your documents)
Many factories worked in MC etc are on site in the A3 drawing. Often I often draw with drawings, sometimes I write notes as well. This is a required item. Feeling of use, rigidity coming from the thickness, just good. As expected.
