Twisting time is here with likely the deepest blind impressions of the bunch. And just to clear the air, Twisted's not confused; it just likes to be a little difficult. And by difficult, we mean, of course, high detail in the countless depths of impressions and a consistent smooth touch on the multiple varied peaked surfaces of the cotton cover stock. If you thought the Life Lines sketchbook was having a party, wait til your 'tips meet Twisted. Once you pull those fingertips away from the cover, you'll page through 24 thick FSC certified (acid free and manufactured with windpower) 70# vellum sheets of stock. Why vellum? Because it picks up graphite effortlessly - test it yourself with the included USA made carpenter's pencil. Actually, the full sketchbook and pencils are all USA made. And because we think protecting something this cared for is a must, we've included a hand stamped 100% cotton pouch with each one. Not so difficult anymore; are you, Twisted?
