This hue will produce a subtle sheening effect when saturated on high-quality papers like Tomoe River and Rhodia. Our color swatch was made with a cotton swab on 68 gsm Tomoe River paper. Color will pull toward a rich blue with more sorbent papers.\nThe 50mL volume will provide approximately 62 standard converter refills assuming a 0.8mL draw.","images":["https://cdn.shopify.com/s/files/1/1237/1088/files/Moon_Jellyfish_a9354c74-836c-4df7-a8f8-37fb22a68233.jpg?v=1737732317","https://cdn.shopify.com/s/files/1/1237/1088/files/Moon_Jellyfish_Macro_Swatch.jpg?v=1737732317","https://cdn.shopify.com/s/files/1/1237/1088/files/InkBottleBox_543850f8-11a5-435b-949f-aa1a4617f474.jpg?v=1737732317"],"price":17,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:18.367Z"},"share_url":"https://firestarter.network/l/lst_22_vabkQ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
