Ideal for watercolor, gouache or inks, and wonderfully compatible with our favorite Nichiban masking tape or liquid frisket.\nWhen our manufacturer gauged our interest in colorful glued edges, we of course replied, \"Well, how many colors can we have?!\" We really didn't anticipate how cute they would turn out—and we're absolutely obsessed! The blocks are glue-bound on all four sides, so your paper stays flat while you paint and as your work dries. Simply insert a bone folder or butter knife in the little window at the top to remove a finished sheet! \n30 sheets / 6\" x 6\" / medium-grained / 140lb / acid-free / natural white","images":["https://cdn.shopify.com/s/files/1/0631/2017/9426/files/CfM-Block-2.png?v=1736798174","https://cdn.shopify.com/s/files/1/0631/2017/9426/files/CfM-Block-Detail_d3098539-ba1e-496a-952f-f3dc2cc80e7f.png?v=1736798174"],"price":30,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:21.757Z"},"share_url":"https://firestarter.network/l/lst_03KPmjy5","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
