TWSBI Vac700R Fountain Pen - IrisThe TWSBI Vac700R Iris comes with a vacuum filler mechanism. This fountain pen features a clear demonstrator body with rainbow colored iridescent trim and a stainless steel nib accented with iridescent color. No two are exactly alike. We felt that it was important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen.
