The pen blanks came from America ( mywoodencreations ) if you go on ebay and put in glow in the dark pen blanks you will see them.
They are not cheap from £4.50 to £7.00 the postage is about £6.50 I have an open mind on these but I am experimenting in making my own blanks.
As woody says in one of the threads they have to be charged up, I believe there is no other way as the crystals used need this light. On the write up on mywoodencreations it says 10min and they will light for a few hours ??????????? yet to prove this.
Are they worth it I don't know at this stage, quite enjoying the challenge and the experimenting, any way they didn't cost me anything
