For your consideration, we are offering for sale this Waterman #7 Brown Keyhole 14K Flexible NIB. The Brown color coded Waterman Nib is known for having a Fine Flexible line. I have had a few of these types of Nibs before and typically flex from a fine to triple broad stroke. The iridium tipping is in excellent condition with the point measuring .58mm when measured with digital calipers. The Nib is for a #7 Waterman Fountain Pen.
