This is the best pencil I own over 400+ mechanical pencils too I use it for
drawing on Bristol Board.
I used to favor the Pentel Kerry but I find my drawing look too Bloopy with it
cause it's wider.
This pencil is perfect except how the metal grip attaches only like 1/3 of a
inch of plastic threads.
Otherwise this pencil is perfect. I own like 18 of these =)
Just bought 5 of these (I know ) I had a few of the grey grip ones but
I like the blue better =) Works really well with worn out dip pen nibs but they
react different make sure to burn the oil off the nib for better flow.
This version the Model 25 works great for delicate lines thinner lines with more
control the the T-40 because it's thinner but it all depends what type of nib
you use also.
I use the T-40 for thicker Key lines and the Model 25 for crosshatching.
The best picked up 5 of these =) They might not work good on traditional
watercolor paper I use it on Bristol board for coloring not really traditional
watercoloring the size of the brush head is equal to like a #5 or #6 brush but
it remains sharp after it dries.
It releases water as you paint trace ammounts or if you squeeze it you can
release drops of water at a time.
Best lead that I ever used anyway works great on Blue line Pro comic boards.
It's slicker then Pentel lead I haven't had it break and I use alot of pressure
with it for drawing. Works great in a Pentel Kerry
