It’s my nephew’s 5th birthday soon and it’s been suggested that I get him some drawing-related stuff - a set of felt-tip pens or the like. But I know what kids can be like so I’m rather concerned for the walls of my brother’s house. Safety is another concern - I don’t want him stabbing someone in a fit of rage.
Are there any felt-tip pens with water-soluble inks? What else would be suitable for a 5-year old?
