This brand is my preferred highlighter, but quality control was deficient in this box of 12.

For me unless it is real obvious that part has not bothered me so far because the highlighter is so good as far as being smooth, bright yellow that does not fade over time like others highlighters and being a liquid you know how much you have left with the handy clear window

One awesome highlighter

The best highlighter is the Zebra Zazzle which has been out of stock for months.
