These are awesome!!! I love the idea of fountain pens but I have a cheaply made beginner one and a pot of ink. That’s not very “on the go.” So, these were recommended to me and they were less than $9 on Amazon, this week. I used them for my 6 pages of journaling tonight and loved them!! They write so smooth and the colors are so opaque and vibrant! I’m going to be hooked on these, for sure!!
