Get over to ebay and put djeco in search someone is selling them for 4.99 + postage I have just ordered some.
They are brilliant....last for ages even with lost lids and I like them as they have two ends, if i need a pen or to write....i can grab one and write easily....colours fab they are the absolute best in my opinon.
I would get the set and the felt tips( from ebay)
I had a set last year the princess one and it went down really well. I love Djeco.
