This British made, A3, portrait sketchbook contains 40 sheets (80 pages) of 150gsm, acid free, premium white cartridge paper. The medium surface makes it suitable for all types of media. Encased in a sturdy, black, hardback cover with a 'soft touch' laminated finish, the notebook is both durable and easy to clean. The paper is sized for wet strength, making it more resistant to bleed through and suitable for a variety of techniques. The large twin wire binding allows the sketchbook to lay flat whilst working and offers space for the sketchbook to expand as it fills with creations. Sourced from sustainable forests, this climate friendly notebook is the perfect choice for anyone looking to be more conscious about the environment.
