The A4 charcoal drawing pad by zieler contains 30 lightly textured, 150 gsm sheets of soft white paper. Suitable for a wide range of uses including drawing with charcoal, chalks, sketching pencils, graphite and oil pastels. Medium weight – the firm texture will help withstand more demanding uses such as scraping of pen nib or multiple erasures. Each sheet is gum-bound at the top of the pad to ensure that each page is secure, yet easy to remove cleanly if desired. A4 size – 210 x 297mm 150 gsm, 30 sheets Acid free
