Several things are nice about these markers: the grip, the colors are spot on and fairly rich for the size of the point. I also like the fact they don't dry out quickly.

i love the fact that these are triangular, makes great for handwriting.

These are perfect markers

These have been great for my 3.5yo who is a serial cap-leaver-offer. Although we haven't had the opportunity to *really* test the 7 day claim on these, he has left the caps off for a bit (less than an hour) and they still work perfectly fine! (Other big name markers definitely dry out in that time.)
