I bought Diamine Shimmering Firefly fountain ink from Truphae via browsing for the best price & fastest shipping. Needed the ink to fill up my Pilot Vanishing Point fp18K F gold nib for a getaway weekend. Chris made sure it was delivered to me on time & the ink was a stunning color. It was perfect for downtime & doodling zen thoughts in a journal, admiring the magnificent views. At the office, I continue to use the pen & Firefly ink for work. Love it.
