{"type":"firestarter.listing","listing":{"id":"lst_FwIcQG_p","product_name":"Dragonfly Twinkle","category":"Ink Bottle","description":"SAVE on Dragonfly Twinkle in the Twinkle Pair.\nInspired by the iridescent allure of a dragonfly wing, Dragonfly Twinkle layers intricate teal tones and glistening Twinkle pigment with subtle merlot accents when saturated on slightly hydrophobic fountain-pen-friendly papers.\nTwinkle Formula inks require additional pen maintenance and cleaning compared to their traditional ink peers. A medium point grade nib or larger is suggested to permit the pigment to travel from reservoir to page. We do not recommend pigmented inks in vintage pens. With all pigmented inks, we suggest using a pen that fully disassembles for complete and thorough cleaning.\nInk swatch and writing samples are produced with cotton swab and medium point grade nib on fountain-pen-friendly Tomoe River paper. Each 90mL volume will provide approximately 112 standard converter refills with an average 0.8mL draw. Rigid glass bottles arrive individually wrapped in cellulose wadding and prepared in a beautifully foiled gift box.","images":["https://cdn.shopify.com/s/files/1/1237/1088/files/Dragonfly_Twinkle_Macro_Swatch.jpg?v=1757436134","https://cdn.shopify.com/s/files/1/1237/1088/files/Dragonfly_Macro_Writing_Sample.jpg?v=1757436134","https://cdn.shopify.com/s/files/1/1237/1088/files/Dragonfly_Twinkle_1550ac5b-96fd-4bf9-93e1-39f15bbfeff6.jpg?v=1782488665","https://cdn.shopify.com/s/files/1/1237/1088/files/Dragonfly_Writing_Sample.jpg?v=1757436134","https://cdn.shopify.com/s/files/1/1237/1088/products/ink-bottle-box.jpg?v=1774542380"],"price":39,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:18.706Z"},"share_url":"https://firestarter.network/l/lst_FwIcQG_p","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
