Made using Crayola crayons from my home by the sea in Pembrokeshire, West Wales. Each crayon is removed from the mould and hand polished before being carefully boxed. Each pack consists of 11 robot crayons of differing colours and a single extra large rainbow shaped crayon. Please choose which colour marbled. These crayons are made to order so colours may vary slightly from the photo shown, however you can request the colour of your rainbow and the robots will always be a rainbow-type spectrum of colours.
