When we use a marker pen，we will find the color we drew is different from the color card showed .True Vision Marker will change existing design of the cap of the pen。Users can colored the cap of the pen by themselves。This can avoid the problem of the chromatic aberration。And users can put the cap on the other side of the pen。It will be more clearly to see and more convenient to use.
