Esterbrook Estie Oversize Fountain Pen - Nouveau Blue CTThe Esterbrook Estie Nouveau Blue fountain pen features a crackled blue resin with either gold or chrome plated trim, in regular or oversize. it was inspired by the colour pallette of art nouveau posters by Alphonse Mucha. The pen looks, to a casual glance in poor light, like a vintagey mottled dark brown colour but on closer inspection features flakes of light blue and light brown, which have a lovely pearlescent quality, seeming to blink on and off
