As part time lecturer, I use a lot of white board markers. Usually the college will give me the branded marker like Artline but I found that those branded markers dries out too fast and the frustration to write on the white board with a half dried marker is enough to spoil my well prepared lectures.
Thus I went to many stationary shops to find for good white board markers. And I found these gems. G'Xin white board markers are very very good indeed. They have the push nib which is for the ink to flow out . When the colour becomes a bit lighter while writing, I just need to press and push the nib a few times on the white board, then more ink will flow out. It is cheap too as compared to Artline and the best of all it does not have that chemical smell as some markers have.
That is not all yet. The best of the best is, I can easily buy refill for these markers. The refills are cheap too. RM 0.65 for one and to put in the refill is a breeze and not messy at all. I am so pleased with the white board markers that I have bought 10 of each colour plus their refills to last me for years.
