Arches watercolor paper, 300g, rough, 12 sheets. - Brand: Arches - Model Name: Aquarelle Watercolour Pad - Number of sheets: 12 sheets - Size: 23 cm x 31 cm (9 in x 12 in) - Weight: 300 g/m² (140 lb) - Paper Type: Rough (Grain Torchon) - Material: 100% Cotton Thank you for looking. I purchased this about a week ago and used only one sheet to try it out. I am selling it because it didn't suit my drawing style. All remaining sheets are unused. I stored it in a ziplock bag with a desiccant to prevent moisture buildup. Please refrain from purchasing if you are concerned about minor details or are very particular, as this is stored by a private individual. Thank you.
