Water soluble and child friendly, the Little Brian Paint Sticks have solid colourful paint that you literally twist up and down, exactly like a glue stick! So, there is no need for water (that always gets dirty!) or brushes (that you only have to clean afterwards!). These super silky paints use strong vibrant colours and can be used on all sorts of surfaces including paper, card, canvas and wood. Wipes easily from windows and whiteboards.
