"I think people who like natural materials are the ones who enjoy the changes that natural materials undergo over time as they are used." Marcello was founded by music teacher Yang Xinyi, who majored in violin. Before creating the bamboo leather bag, she never imagined that tanned leather could be such a harmonious match with bamboo. She discovered that just as leather gradually changes shape based on the temperature and oils of a person's skin over the course of its use, bamboo also adapts to each person's touch, accumulating unique beauty and flavor over time. “Leather, like bamboo, has its own unique style with each use.” Echinous leather is less common in the East, while bamboo is almost non-existent in the West. The bamboo-woven leather bag thus becomes a fusion of East and West, reflecting the relationship between the founder and the gentleman from Taiwan and the one from the United States. Bamboo is destined to solve the material dilemma of leather. Marcello chose to use tanned leather because it is closer to the natural material of bamboo and retains the softness of leather. Taking advantage of the structural beauty of bamboo and the support provided by the bamboo weave, Marcello uses the square-woven bamboo technique to support the surface of the tanned leather, presenting the visual elements of bamboo and leather in an interlaced logic. Compared to fabric materials, tanned leather is difficult to stretch, which can lead to problems such as shrinking. However, guting bamboo leather can provide structural support for tanned leather, making the garment firmer and the patterns more orderly. In fact, the addition of bamboo has improved the durability of the leather bag. This was something we hadn’t originally planned. Initially attracted by the beauty of the fusion of bamboo and tanned leather elements, Yang Jinyi researched and made the product with the help of bamboo artisans. Unexpectedly, she discovered that the finished product could improve the functionality of the leather item, and she decided to quit her job as a music teacher to focus on designing bamboo leather products. The first person is hard-working, but is also an adventurer who pioneers the market. The combination of bamboo and leather is not widely accepted, and market education is difficult, but this also means that bamboo leather bags are an innovative product. Even with the difficulties of brand management and market education, Ms. Xiyi and Mr. Chen still believe that as long as they keep working hard, they can make people feel the beauty of combining bamboo leather with Western materials, and open up the market to wider recognition.
