This laminated poster is so convenient underhand I ordered a second that I also use in the office to review "casually" my meridians ... However it should be noted some small errors in the localization of certain points. But overall, it is very well done: the meridians are prominently visible by their colors, ancient shu points are also marked with the colors of the corresponding elements. It would be perfect without these small shells, hence 4 stars only, but I highly recommend.
