I love the quality of Staedtler products and these highlighters follow suit

Same great quality that can be expected from Staedtler.

But this is why I gave them 4 stars, I think this is great quality INK, but but of being a great quality PRODUCT includes quality packaging, as well

These are very good quality highlighters

The Textsurfer Classic Highlighters , 18 Colored Highlighter Set—is one of the better quality highlighter products.

this are excellent quality, bright easy to work with and they actually do NOT make the ink bleed when used on Xeroxed copies.

The colors are bright when on paper! great quality!

This was THE FIRST TIME EVER that a highlighter has not smeared ink on my typed notes as well as in my textbooks
