The 18pc Fine Coloured Sharpie Set from Artworx Geelong contains 18 1.0mm fine bullet tip shades which are also non toxic and work great for children’s art supplies boxes. These Sharpie markers are guaranteed to not dry out if uncapped after 30 minutes but if they are slightly dry simply put the lid on and leave them overnight and they will return to the permanent Sharpie you know and love.
