Other reviews have criticised this pack for a lack of variety. The purchaser obviously didn't read the details adequately. Of course the majority are the more normal shades - black, blue, red - the ones used regularly and therefore running out fairly quickly. Then there is a good selection of fab shades, to enliven writing, presentation, whatever. I use them to avoid marking in red all the time. Using a different colour each time I mark students' books makes it fun for my pupils (and me!) and also highlights regularity of marking. What's more, the pens write beautifully and are fantastic value.
