I have bought 3 sets of these now.  The first was for me, the other 2 have been presents.  These are probably some of the best thin-tipped markers on the market for a reasonable price.  The colors are super bright and true.  They don't skip.  The tips don't fray with use - this is HUGE.  I do wish there was a hair more color variety in the set, especially around the yellows/browns, but I can't really complain for the price.  These are a fantastic choice for adults for coloring books or doodling, as well as for kids who want a step up from Crayola.  Well worth purchasing.
