This set of 12 coloured pens come in their own storage package with press stud closure.
They are well made and feel balanced and robust in the hand.
Each has a 0.4mm metal clad fine tip, writes smoothly and precisely.
They would be great for art students and budding artists as well as using for graphs etc.
They are a little on the expensive side but all in all they are fit for purpose.
I have not been using long enough to comment on longevity but would expect them to be long lasting.
I hope this review helps others to make a more informed decison when purchasing as the reviews of others are invaluale to me.
