I wanted to get an inexpensive set of alcohol ink markers for when I travel so I don't have to worry about losing my Copics. This set from Amazon was about $30 for 120 of them and they work pretty well, made by Sanjoki of Japan. There is a little bit of bleed to them so you have to be careful near the edges of your image. I really like their assortment of greens, I can never seem to find the shade I'm looking for a lot of the time. The naming of the colors in this set is a bit odd so I will be going by the color chart when choosing.
Of course I won't be taking the whole set with me, it's pretty heavy!
