The quality of these china markers has dropped a lot compared to what they were. I have been using these for over 30 years and this will be the last time I purchase them. My main complaint is the material the wax is made of. They used to be very smooth to use. Now they feel like there is sand in them and have a terrible drag to them. You can even hear them scratching as you use them. Secondly, they do not tear right after you pull the string to expose the new end. It is a pain to try to get all of the old paper off. The diameter of the wax is smaller than my old ones. It might not be much but it is obvious when you look at them. It is just surprising something so simple could go down so much in quality. It is a case of a company trying to save a few cents at the expense of losing a reputation of quality that takes years to build.
