Children''s marker / Marker pen

Children''s marker
Children''s marker

This is a marker for children. Put the red, yellow and blue tubes into the marker pen, then adjust the mixed color slider on the marker pen, adjust the mixing ratio of the red, yellow and blue tricolor, and get different colors. And the color solution can be preserved. The marker only needs to replace the color tube, which reduces the waste of resources and is more convenient to carry and use. At the same time, it can cultivate children's ability to recognize and match colors, so that children can learn colors from childhood and fall in love with colors.
