Can't fully comment as I bought the metallic ones as a gift, so haven't personally used. I did however buy the plainer colours in the 6 pack and they are marvelous. Have done a fair bit of writing already with them and they seem to be lasting well. The gel glides on smoothly and the choices in colour are fantastic if you need to make notes which you can vary in importance by choosing different colours. The pens are comfortable to hold and gentle of the hand with the fatter grip area. Great for kids and adults alike and really wish I had bought the metallic for myself as well, but will do that soon. Great price. Highly recommend.
