Types of Leather

Posted by Tatiana Pestarino on

Not all leathers are the same. There are many different types and qualities. The same leather is divided into layers, with the highest quality being the top and the lowest the bottom. 

We use the best leather to manufacture our pieces. As it is full grain, it is the most resistant and durable leather. The tanning process is vegetable, using natural tannins that do not pollute the environment.



  Full Grain Leather: Casia Leather

The outermost layer of the skin, the toughest and most durable, which gives it qualities such as waterproofing and resistance to wear. It also ages over time, and along with the inherent imperfections of the animal's skin, gives each piece a unique appearance.

   Top Grain Leather:

Although it doesn't reach the level of durability of full grain leather, it is still high-quality leather with the added benefit of greater flexibility. It is highly versatile and easier to transform.

  Genuine Leather (or Corrected Grain Leather):

This is the leather that remains after removing the top layers. It is often processed to eliminate imperfections and a coating is applied to mimic the appearance of full grain leather. It is flexible and smooth.

  Bonded Leather (a type of conglomerate made from leather scraps).

We design our brand with the premise of responsible consumption. We create durable and timeless objects that improve with use by selecting the best raw materials from our country.

Through simple designs, we let the material take the spotlight while respecting its identity. That's why we use vegetable-tanned leather without altering it. To us, its marks are nothing but signs of its history and your own story as you use it.

  That's why we use full-grain leather.

It's the outermost part of the skin, the toughest and most durable, giving it qualities like waterproofing and resistance to wear. It has the most distinctive character. Furthermore, it ages over time, and along with the natural imperfections that come with the animal's skin, it gives each piece a unique appearance.


The properties of full-grain leather derive from the animal's skin it comes from. Because it's not trimmed to remove imperfections or make it thinner, it shows scratches, imperfections, or marks from the animal's live activities. Full-grain leather looks better over time as it absorbs oils and develops a patina with handling.


All full-grain leather will bear the scratches and imperfections resulting from the animal's natural activities, such as insect bites and rubbing against a fence. When crafting high-quality pieces, obvious defective leathers won't be used, but even the best-quality ones will have minor imperfections. These imperfections add to the uniqueness of each leather piece. The appearance of the leather tells the story of the animal, tracing its history through the marks and stains left by each event.

Vegetable Tanning

"We use bridge leather, which is vegetable-tanned leather, where no chemicals are used in the process of transforming raw leather into usable leather. Instead, tannin is used, which is a substance extracted from the bark of certain trees like quebracho."

"From the beginning, we were clear that quality should be one of our pillars, so we only use raw materials of national origin, based on vegetable-tanned bridge leather, which stands out for not using chemical products in the production process, but rather tannin."

  • Vegetable-tanned leather has unique variations and characteristic marks that result from a process where the leather is not artificially embossed to achieve uniformity. These variations are not flaws but rather evidence of a living material without finishes that conceal its nature.

  • The vegetable tanning process is a very ancient technique that results in leather that is strong and resistant to the passage of time.

  • We recommend storing our pieces in well-ventilated areas.

  • Contact with inks, water, perfumes, makeup, alcohol, oils, and solvents can cause stains on the leather.

  • Prolonged exposure to sunlight can darken the leather.

  • If the leather gets dirty, we suggest cleaning it with a soft, dry, white cloth.

  • Over time and with use, the natural oils of the leather rise to the surface, creating a patina that smoothens out the original scratches or any scratches that may have accumulated with use.
