Long life, don't dry out (haven't left them uncapped for long periods mind you), excellent colors to really make your notes stand out. Doesn't bleed through the page either. With these you can highlight with thick lines or used the chiseled tip to do underlining. Only drawback is the company logo wears off quickly from the plastic highlighter body but I didn't buy these to look pretty...I will be ordering more when these dry out. Cheers!

Great price and quality
