I think it is honey, I am going to research Used for pens in my back pack, no marks inside from them. Great used condition! I have tried to document the condition of this item as best as possible through photos, but if you have any questions please ask! As with all PLG items, made from real full grain leather and the unique texture and natural imperfections from the cow's life have not been sanded, cut or shaved off. See photos for texture and condition. Alpine measurements (from website): Width: 7.5” Height: 3.75” Depth: 3.25”
