I bought these paints for my father 25 years ago. He never used them. They have been sealed in a sellophane wrapper, which I have just opened to see if they are still soft. Either end are, but the yellows have gone hard, and the greens are going that way also. But the  blue end and the brown/red end seem fine. Just want them to go to someone who can use the remaining colours or reconstitute the others.
