Stillman & Birn : Zeta Softcover Sketchbooks : 270gsm : Smooth

Stillman & Birn Zeta Softcover Sketchbooks are flexible yet strong, with sewn bindings and rounded corners that help prevent the edges from fraying. Their softcover format makes them practical for carrying while still offering a durable structure for regular use.

They contain extra-heavy 270gsm white paper with a smooth surface suitable for pen and ink as well as dry media. With both internal and surface sizing, the paper can also accept light washes, wet media, and watercolor. The paper is pH neutral and free from lignin and chloride.
