Refillable Technical Drawing Pens Needle Pen Set 0.1-1.2mm (9 Pens)

They do the job. But the over all appearance is tacky and cheap. Should have gone for something else.

Was hoping they were the same as the fine felt tipped pens i got in a set just refillable, i was wrong, the pen is not for hand held work there is no end on the needle to regulate the flow of ink, the ink would flow when it wanted not when i wanted it to, stop and start then have to shake it and splatters all over the paper, the only pen i could get to work on all the types of paper i want to use was the 1.2. only good thing you can clean the pen out with water. i will keep them but not for ink am thinking watercolour is the best thing
