Pigment mixing pen

There is an old Chinese saying: "It is better to teach fish than to offer fish". In areas where materials are extremely scarce, when the color lead and watercolor pens or other color painting tools provided by the outside world are used up. This "pigment mixing pen" can provide methods and media for children to obtain natural pigments permanently by crushing plant stems, leaves, fruits and other parts and adding water to turn them into natural pigments.
