Newplast skin tones
Whilst not as well known as its more famous forebear, this is actually its animation grade equivalent, used by Aardman for Wallace & Gromit, Chicken Run, Shaun the Sheep etc. as well as more esoterically in the development of industrial prototypes, and manufacture of MRI scanners. Of course it still performs just as well as a toy, being non-drying, non-toxic, and near infinitely reusable. and unlike the other it's still made in the UK. Available in either 500 gram rainbow or skin tone packs.
