Plan D Tube Fly Mandrels are made from 316 marine grade stainless steel and come 20
to a bag and in three different sizes:
§ Small (.065mm o.d.) Our smallest mandrel. It is a little bendy but will fit most
small tubes even if they have been partially crushed or the nose holes were melted
without being reamed by a mandrel when still hot.
§ Medium (.08mm o.d.) Fits most micro tubing and Pro Tubes
