Thank you for finding this. These are crow feathers I saved, hoping they could become quill pens. If anyone needs them, I'm happy to give them away ^-^ I've included eye drops for a size comparison, though I'm not sure if it helps. The eye drops are not included with the product. Maximum length: Approximately 31cm Will be shipped in a clear file via Yu-packet. Base disinfected. #crow #crow #raven #feather #quillpen #black #dancer #stagecostume #indian #biker #magic #sorcery Thank you for looking.
