Each set contains 4 or 5 primary wing feathers from a wild greylag goose. Most of the sets have matching pairs, 1 set of large feathers and a smaller set. The extra smaller feathers were added to the 2 pair. They are mostly photograghed from the rear, as they do not want to sit well with the good side up. Ideal for herl bodies and the grey goose nymph. If you would like a specific set, please let me know the photograph number and I will try and oblige. I will take the photo down of sold sets.
