Royal & Langnickel - Pentalic Traveler Pocket Journal - Sketch/Blank

I've loved this line if sketchbooks since i found a smaller one that was half price; i swatched it with every fine liner, fude, and brush pen i own (Copic, Faber-Castell, Winsor and Newton, Uni, Derwent, Tombow, and Kuretake), plus my boyfriend's fountain pens, and experienced no bleed through or blotchiness. i use a VERY light wash of watercolour or ink on some of my sketches, and the paper wrinkles a bit, of course, but does not buckle. its slightly textured, so i can blend my gel crayons a bit, too, but so smooth my pens glide across it, and the paper weight is perfect for my use. i often use 2 page spreads, and i prefer a soft cover as it allows the book to lay close to flat, the band holds it closed and makes sure pages don't fly on a windy day, and i always find random things to lut in the little pocket at the back. the 3x4 is nice to slip in my pocket with a brush pen, 4x6 size is perfect to toss in my tote along with my pen bag for random sketch time, this 8x6 size is small enough to go with me, but big enough to ensure i have plenty of room for more finished sketching, and i use the 8x10 size to do sketch studies at home. i love these! please note that i don't use pencil, so i can't confirm, but heard it does not erase well. otherwise, perfect sketch book.
