Jumper leads

I have found that I am using a lot of the common colors and need some more of Red, Green, Yellow, Blue and Black ones. I am looking for about a 10 or 12 of each, but I can’t find them specifically. There is a shed load of links for jumper leads but they are all various colors and not enough of the ones I want.

Does anyone know where I might get what I want.

I have found some decent quality ones, I hope, on Farnell’s site but they are fairly expensive, running at approx £8 for about 10.

I’ll keep looking
