Octopus Fluids Resin Inks are fast-drying alcohol-based colour concentrates that have been specially developed for colouring epoxy resin, UV resin, acrylic resin, polyester resin and other casting resin systems. They are extremely productive and give the resin an intensive colouring. This makes the colours excellent for making cast resin jewellery, resin coasters and the popular petri dish art. All colours can be easily combined with each other and also with our Alcohol Inks.
