Big Waste of Money.  Sent these back.  So disappointed.  The tips feather and leave fuzziness behind and you have to "clean" the tips before reusing to wipe off the fuzz.  Colors were okay but 30 out of 36 had fuzz issues so these were no good for me.  The Bic Mark-It markers (both ultra fine and fine) were 3,000 times better than these and the colors were better too.
