I split the 300 markers between three classrooms and we're still working through them months later. The fine tips haven't frayed or dried out, even on the ones the kids leave uncapped overnight.

Bought the 100-pack case for our church office and the fine tips are holding up well after a month of daily envelope labeling. Three hundred markers means nobody's ever hunting for one when they need it.

Split a 3-pack between my desk, the garage, and my daughter's craft bin, and all three still write a crisp fine line without drying out. For 300 markers the price per pack is honestly hard to beat.
