The product is great. I ordered these pens in every available colour for my daughter to use for school and she loves them. My only issue is that when I ordered them on the website clearly shows a box of 12 pens as a unit and when I received my order I only received 1 pen of each colour. Very disappointed as I was expecting 12 pens of each colour. When I reached out to customer service, I was told that it's only for 1 pen, despite the picture showing a box of them.

The best erasable pen! slide very well on papel, crisp color and not much trace after beeing erase. 10 time better than papermate

I use these pens for making comments on student work. Only wish the ink supply lasted a bit longer.
