Our rubber's colours are as vivid as life itself: not only black or white, but sometimes bright yellow or deep blue. Or red, pink, purple. And turquoise and free of plastics - as our oceans should be. Thus our rubber is made of natural caoutchouc which contains no plasticizer or chemicals based on petrochemistry. This set contains a rubber in purple, turquoise and white. Colour it up! Don’t combine with oils.
