I really like these markers and definitely would recommend. They are superb for drawing. The fat tip is good for laying down large areas of black and bold thick lines. The skinny tip is good for adding detail and light lines for contrast. There is minimal odor when using for a long period of time. Great product!
I have been please with the TRU RED permanent marker pen. I have found that the ink flows more easily than in the Sharpie brand and I like the fact that it has two different size tips in one pen.
