Good quality.

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.
