I love this drawing pads. The paper is so nice to work on. It's a very forgiving surface that doesn't frill from multiple use of erasure and the finished work is always looking more professional.
The 8" x 10" size I bought feels somehow natural and very convenient to carry around without being too big or too small.
I strongly recommended Strathmore 400 Series drawing paper to my friends and I believe it didn't took too much of an effort to persuade them as the drawing's results was speaking for themselves.
