Uncharted Mix Small Stick 18 Soft Pastel Set

The Uncharted Mix 18 set contains 18 unique soft pastels in neutral colours. Uncharted sets are made up from pastels that missed their original colour criteria, but are still made up of the same beautiful pigment.

Uncharted sets are random, the colours are anonymous and can’t be replicated and each box will be a surprise!

Your Chance To Grab Some Genuine Unison Colour Soft Pastels At An Unbelievable Price.

Our founder John Hersey found inspiration in the clarity of light and subtlety of colours from the Northumberland landscape, creating his own range of soft pastels in the 1980’s.

We still use John’s original testing system, to make sure each pastel sold today is an exact match to John’s original charts.

If, during our handmade production process, a pastel does not match John’s intended colour, they’ve been put to one side.

But these pastels contain the same beautiful pigments.

They’ve all been made by hand with the same love and care.

They deserve to be used.

And we’ve built up quite a stock of them over the years…

That’s why we’re announcing three limited edition batches of ‘Uncharted’ Unison Colour soft pastels.

They’re ‘Uncharted’ because they won’t match any of our 380 ‘official’ colours.

But they’re still 100% Unison Colour handmade soft pastels.

We’ve raided our shelves and put together three sets, each containing 18 ‘Uncharted’ pastels.

To help you decide, one set contains 18 Warm colours, one set contains 18 Cool colours and the final one contains 18 mixed colours.

We can guarantee each set will contain 18 beautiful and unique handmade Unison Colour soft pastels.

But unlike our normal sets we can’t guarantee exactly what colours your box of pastels will contain.

But that’s quite exciting! You won’t know what you’re getting until you open the box!

We only have a limited number of sets and as you’d expect – when they’re gone, they’re gone.

It’s taken many years to build up the ‘Uncharted’ stock so we won’t be in a position to do this again for quite some time.

So are you going to take advantage and grab some ‘Uncharted’ Unison Colour handmade soft pastels before they’re gone?

Although the pastels offered as Uncharted Sets by Unison Colour contain the same superior pigment ingredients as our existing range, they have not been subjected to the customary rigorous testing and approval of a toxicologist. They will nevertheless produce great results and the colours offered are uniquely non-replicable.

This does not affect customer statutory rights for a refund if not completely satisfied.

Please do bear in mind that our pastels are hand made from a variety of traditional pigments, all of which have their own characteristics. This means that size does fluctuate ever so slightly, and the softness varies between the different colours. We do, of course, keep well within our criteria for the perfect pastel, but if the pastels you’ve received don’t quite live up to your expectations, please get in touch and we’ll make sure it’s put right.
