These really don’t bleed/ show too badly through college ruled or lined paper (or the regular printed paper as shown in my pictures) that I don’t write on both sides of the pages and I LOVE them for school work. Have made my life so much easier and prettier! They glide much easier than regular pens.
I also love that they seem to never dry out despite the fact that I’ve been using them at least 2 weeks now and have left the most used black marker open for several long periods already, coming back to still find plenty of ink and no change in the writing ability.
I think these are great quality pens and definitely worth your purchase.
