Have ordered for my whiteboard the pins and am extremely happy with it. The pins can thin but also thick write, depending on which is written with angle. The only drawback for me is the sponge that wipes Although the font, but only superficially, so you still with a handkerchief or similar wipe needs. While it can also be due to my board, is with me but now times a fact.
Conclusion: The pins are simply superb, for 5 star, unfortunately a star deduction for the sponge.
