Disappointed
I couldn't wait to use these, watched every episode in the class and went back to make sure I stored and used the pens properly. I tried every pen exactly as directed and they worked perfectly. I went back a couple of days later to use again and they started leaking above the metal tip I thought I might have received a bad batch but when it happened to all of them, I was sure this was not made correctly. The ink came out in blobs.
