These markers seem to last a long time if you take care to cap them as soon as you are finished with them. You also need to avoid getting the tips wet, which will stop the ink from flowing. We have tried a lot of different pens and markers for writing on plastic and have had limited success. Many pens seem to take forever to dry or will not mark on plastic. So far Sharpie permanent fine-point and ultra fine-point markers avoid these problems and provide sharp print for nearly all labeling needs.
