Yes, there are different types of leather used in wallet production. Full-grain leather is considered the highest quality and most durable, which is what Trayvax uses. It retains the natural grain and imperfections of the hide, showcasing its authentic character. Top-grain leather is another popular choice, which undergoes a process to remove the outer layer and achieve a more uniform appearance. Other types include genuine leather, which is made from layers of lower-quality leather bonded together, and exotic leathers such as crocodile or ostrich, known for their unique patterns and textures. Each type of leather has its own qualities, and the choice depends on personal preferences and budget.
