The box says SP-9711 which I used over a year ago (I kept the label). They were about 7/8 tall when I last bought them. That's a little less than 3/4 of a quarter (23rd/32nd). They don't match the project I bought them for. Now I'm stuck with nibs I can't use and looking for nibs that will work for my craft. I doubt I will buy anything from this manufacturer again.
