Pens for clothes labels

[CookieMonster2]

Can someone recommend a pen that can be used to write childrens names on the labels of their clothes?

I have got some of the sew in labels but don't want to use these for every pair of pants/vest etc, and I have discovered that biro washes of after a couple of washes!

Thanks.

I bought one in mothercare ages ago that does the trick. Also there are iron labels too - feck sewing!

Thanks. I'll give Mothercare a go at the weekend. It has to be cheaper than losing clothes at nursery!

I got a pack of 2 with my Ocado shopping last week they are John Lewis ones and work perfectly - I sew and write in all DDs stuff as the parents at her school seem to have no scruples and I am feckin sick of her losing jumpers that are named - have threatened to write her name across her chest on her jumper as a sort of protest if they don;t address the theiving bastards soon!
