What to say about this article? after having received very quickly (the day of the order), I tried this on my whiteboard markers: nickel writing, erasing perfect. RAS. These are small markers, firm tip, the line thickness of about 1mm (or plsu if pressed). No idea of their service life. It is advisable to keep them horizontally
tip for erasing: if you have not cleared a table for a long time, the ink dry a little (this is normal), and it's harder to completely erase the trace. In this case, do not worry, just pass a cloth soaked in acetone and Table shines without a trace.
