These beautiful 1 oz. (30 ml.) storage jars might look like antiques, but unlike the hinged cap inkwells of the 19th century, their lined pewter caps have a modern air-tight seal. Besides being a lovely inkwell, these glass jars safely store your calligraphy ink as well as your moisturizer, medications, essential oils, paper clips, beads, the list goes on!
