Barb Structure

Pennaceous upper portion with tightly interlocked barbs and barbicels, transitioning to a plumulaceous (fluffy) downy base with distinct aftershaft

Texture & Surface

Smooth, firm, and matte texture along the pennaceous vane, with a soft, fluffy downy base near the calamus

Key Features
