Bests & Worsts Reviews from Amazon

When I bought these pens I was SUPER excited. I loved them- the pigment was good and they erased completely. I told everyone about them... And now I will never use them again. The ink in two journals that I used these pens in has almost COMPLETEY disappeared. I have lost all of my notes in my preparation of a trip to Ethiopia I am going on and cannot get them back. DO NOT USE THESE FOR ANYTHING IMPORTANT! the journal was NOT rubbed, and was kept inside on the ground untouched for about 2 months after I used it.. When I went back to read my notes they were gone. I have attached a picture. This happened in another journal too, so I know it was not the type of paper. :( very disappointed.
