Ostrich leather can very easily be distinguished from bovine leather. Firstly, the skin is much smaller at an average size of 14-16ft². It also stands out from bovine leather due to its unique quill pattern, that gives the leather a hill and valley or goose bump appearance. The bumps are formed by feather follicles that close into quills after the feathers are removed. These quills are clearly visible in a diamond shape that covers the centre area of the ostrich skin known as the “crown”. In total, about 55% of the skin is covered in quills, which include the crown, neck and belly areas. The smooth areas are from the skin located below the wings which is not covered in feathers. Ostrich leather is not split into layers and is a full grain leather from which corrected grain leather will not normally be produced. 鸵鸟皮可以很容易地与牛皮区别开来。首先，鸵鸟皮尺寸要小得多，平均仅14-16平方英尺。由 于其独特的毛孔纹路，外观上呈现出山丘和沟壑状的或类似于鸡皮状的凸起效果，令鸵鸟皮与牛 皮大不相同。这些凸起由羽毛毛囊形成，拔出羽毛后毛囊收缩成毛孔。毛孔明显呈钻石形状，覆 盖鸵鸟皮的中央区域，即皇冠毛囊区域（“crown”）。皮料上共约55%的部分覆盖毛孔，包括皇冠 毛囊区域、颈部和腹部区域。皮料上的光滑区域位于翅膀下方没有羽毛覆盖的地方。鸵鸟皮不可 剖层，是一种全粒面皮革，通常不会用于制作修面革。 Ostrich leather is an exotic leather, making it much more sought after and expensive than normal cowhide leather. Ostrich leather is considered to be one of the finest and most durable leathers. 鸵鸟皮是一种稀有皮革，因此比普通的牛皮革更受追捧，价格也更加昂贵。鸵鸟皮被认为是最优 质、最耐用的皮革之一。
Ostrich Quill Follicles 鸵鸟皮的毛孔毛囊
The quills of each ostrich skin are unique and make it a sought-after exotic. Well-developed quills are the result of full-grown feathers that create a follicle on the skin that is rounded and closed. Development of feather follicles is genetically determined and differ from skin to skin. Feather follicles are generally not considered in the grading of the skin, except where follicles (quills) are visibly damaged due to defects caused by severely under-developed quills or in-grown feathers. 每一张鸵鸟皮的毛孔都是与众不同的，使其成为备受追捧的稀有皮革。毛孔发育完好源于羽毛发 育成熟，在皮肤上形成圆润闭合的毛囊。毛囊的发育是由遗传决定的，每张鸵鸟皮各不相同。皮 料分级时通常不考虑毛囊形状，除非毛囊严重发育不良或毛囊内有严重缺陷，导致毛囊（毛孔） 明显受损。
