I used it some years ago and I like to write on whiteboard, I have still one till this time
This is one of the great products that the teachers of my area use so it is better or I should say best for whiteboard teaching purpose. And I have used it also sometimes for teaching too when I used to teach children under 5 years.
Tht's great stationary product and its refill too.
I have to say only one thing here , its size is thick and I don't like its thickness.
