I bought a 24 pack of coloured permanent markers on the weekend so i had to test them out. It's nothing huge because i didn't want to go all intricate just for the pens to end up terrible. 
my verdict- They are awesome. i love them. 

The creation!

I drew a chibi mermaid. I was originally going to draw an anime character but i like having a reference for those. My sister then mentioned something and for some reason i thought of fish, then a mermaid. Next 30 minutes was how the mermaid would look and this is the end result. 
Enjoy!
