100%義大利真皮

使用保留牛革天然紋路的頂極面皮，所以皮紋天然件件不同。100%真皮皮革所製成，也就是使用“牛隻的表面皮革”稱之為「會呼吸的皮革」。未經加工處理的牛革，保留牛革的天然紋路，件件不同，獨一無二。

Highest Quality Italian Leather
By using the best quality Italian leather, which preserves the natural grain from animal hides – usually from cow skin, it also called “the breathable leather”. Without chemical-laden processing, leather is able to maintain its natural, organic look and feel throughout the craftsmanship.

天然皮革紋路

COWA的皮革最大的優點，就是使用『牛隻的表面皮革』，除了皮革仍呈機體狀，皮革會呼吸透氣外，更有人工合成皮無法取代的天然紋路。由於成品在製作過程中所採用的皮革部位均不同，所以無法使每一件成品的紋路一致。尤其是採用牛隻「腹部」、「頸部」等所製出的成品，最容易在使用過後，出現深深的『使用紋』，一如人類的抬頭紋、魚尾紋。

Natural Texture
To maintain the natural look and being breathable, the natural of our leather is irreplaceable. Surface texture is often lessened or standardized throughout manufacturing processes of leather goods. Texture on the other hand can be unique and genuine during handcrafting process and by using different parts; for instance, cattle stomach or neck are usually deepen an mellow over times through uses.

植鞣革－為環保盡一份心的無垢材

無垢材保留材質本身優點，不假過多修飾、加工，無化學添加、無污染，自然、純淨之清新素材。
COWA堅持植物鞣染的製革技術，這種染色方式，會先從植物中萃取一種單寧酸的汁液。這種汁液一旦與皮革接觸，能產生一種物理催化作用，使皮革變色。用手一次又一次的將染料和皮革揉合“By hand again and again.”的技術就叫做植物鞣革。其最大的優點除了保留皮革天然的特色外，更有別於化學鉻染，不會破壞環境及危害人體健康。

Environmental Friendliness
With all natural, free from artificial and excessive treatments and process, it is eco-friendly; which refers to our brand- COWA’s core value, to preserve the natural characteristics of genuine, highest quality leather and manufacture with best craftsmanship while protecting our environment.
By extracting tanning acid from plants, vegetable-tanned techniques create chemo-catalysis and change the colour of leather, which processed by hands repeatedly.
The most salient advantages of vegetable-tanned leather is the capability to maintain the natural texture while completely environmental friendly.
