BUNGUBOX inks come in their delightful and original heel-shaped bottles! The unique box packaging allows you to tilt the bottle at an angle when it’s running low, for easy dipping. 

Iron Gall Ink is a water-soluble ink that contains a combination of tannin, a plant-derived component found in tea leaves, and iron. These materials oxidize when they are exposed to air, giving them water and light resistance for greater durability.  The oxidization process also causes a color change, gradually turning the vivid color of the ink to a deeper blackish hue over time. 

"Blue Marine" is a vibrant, striking blue that gradually transforms into a deep, rich blue as it oxidizes on the page. It mirrors the ever-changing surface of the sea. We've captured the ocean's beauty in this ink. Wouldn't it make a wonderful addition to your collection?
