Hi All

Thanks for your replies sorry it has taken so long for me to respond, Ive only been popping on for a couple of minutes a day.

Thanks all for your advice I just wanted to clarify that I have put them only on the bullet end not the chisel end, i think you could be right about the pens maybe running out as I have put it on a brand new pen and ink flowed straight through.

Thanks again for your help and advice, and thanks Joanna for the offer but I wouldn't send them back it probably is just my pens running out, after all they get used all the time.

Cheers
Kelly
