This starter set from IRHSP gives you their complete range of flash colour bases. They can be used on their own or mixed with darker/lighter colurs to give you a whole new range of flesh tones to suite your project.
Bake at 130C to ensure they cure.
They need to be thinned down before use with either odourless thinners or Liquithin.  You must NOT use water as these paints are oil based.
