{"type":"firestarter.listing","listing":{"id":"lst_Uh0iUWf_","product_name":"ALL GRANULATING PALETTE","category":"Watercolor paints","description":"19 of the most astonishing granulating colours that are deeply inspiring, that will be functional as well as magical on any artist's palette. You’ll get a free tin box with every purchase of this watercolour set! \n\nA compact tin box which is perfect for plein air painters, or just as a nice home for all your precious colours! \n\nIt is natural for some paints to have cracked surfaces by their nature. However, we assure you, that the cracks don't affect the performance of the paints.\nEach pan is magnetised. The paints come in their individual portable tin boxes. All tin boxes in our shop are shipped in upcycled, colourful cotton bags, which you can reuse in any manner you wish. Since the bags are upcycled, we can't promise everybody the same kind of bag.","images":["https://cdn.shopify.com/s/files/1/0873/6548/4857/files/blue-pine-arts-premium-art-supplies-handmade-artisanal-watercolor-paints-professional-handcrafted-watercolour-sets-all-granulating-8876.jpg?v=1715149647","https://cdn.shopify.com/s/files/1/0873/6548/4857/files/blue-pine-arts-premium-art-supplies-handmade-artisanal-watercolor-paints-professional-handcrafted-watercolour-sets-all-granulating-8874.jpg?v=1715149647","https://cdn.shopify.com/s/files/1/0873/6548/4857/files/blue-pine-arts-premium-art-supplies-handmade-artisanal-watercolor-paints-professional-handcrafted-watercolour-sets-all-granulating-8879.jpg?v=1715149647","https://cdn.shopify.com/s/files/1/0873/6548/4857/files/blue-pine-arts-premium-art-supplies-handmade-artisanal-watercolor-paints-professional-handcrafted-watercolour-sets-all-granulating-8882.jpg?v=1715149647","https://cdn.shopify.com/s/files/1/0873/6548/4857/files/blue-pine-arts-premium-art-supplies-handmade-artisanal-watercolor-paints-professional-handcrafted-watercolour-sets-all-granulating-8884.jpg?v=1715149647","https://cdn.shopify.com/s/files/1/0873/6548/4857/files/blue-pine-arts-premium-art-supplies-handmade-artisanal-watercolor-paints-professional-handcrafted-watercolour-sets-all-granulating-8889.jpg?v=1715149647","https://cdn.shopify.com/s/files/1/0873/6548/4857/files/blue-pine-arts-premium-art-supplies-handmade-artisanal-watercolor-paints-professional-handcrafted-watercolour-sets-all-granulating-8895.jpg?v=1715358186"],"price":233,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:20.528Z"},"share_url":"https://firestarter.network/l/lst_Uh0iUWf_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
