8 x Magic Colour Swap Change Fibre Pens School Art Felt Tip Colouring Assorted

I'm really disappointed with these pens. I bought them for my daughter for her birthday and she was very excited to use them but the white pen does not make the colour change on half of the pens and the ones it does change (dark blue to light blue, for example, are only a slight variation on the colour. Definitely would not recommend these and would not buy again.

Do not buy they Do NOT work!
