Our Story

“In design we have a tool through which we can present solutions to existing problems as well as ensuring cultural diversity worldwide.”


The Brand

Concalma is a distinct brand founded in 2006 that has had great customer acceptance and has proven to be resilient. The competitive advantage of Concalma comes from the consolidation achieved at Concalma The Store, a brick-and-mortar operation that supplies quality designer products, including its best selling product line of tote bags designed by Concalma's founder Matilsha Marxuach. The bags are manufactured at an industrial women-owned factory in Utuado, Puerto Rico. The store also supports products of other local designers. The communication strategy of Concalma aims to raise awareness of fair trade, the importance of local design and manufacturing as well as promoting sustainable practices. Concalma’s mission is to combine functionality, quality and creative design into its products with sustainable, social and responsible actions, creating a unique bundle of physical, emotional and conceptual values.


The Store

Concalma is a designer brand with a brick-and-mortar store strategically located in the heart of Old San Juan (207 San Francisco Street) that serves as a marketplace for its own product line of designer tote bags and distributes products of other local designers as well. Our store presence has represented design, innovation, entrepreneurship, fair trade and local production.


The Bags

The Concalma handbag line is made up of 16 different styles of cloth bags and totes designed by founder Matilsha Marxuach. The bags are made out of fabric and the wide, comfortable and athletic handles plus colorful fabric choices and combinations are some of Concalma’s trademarks. The handbags are used as an everyday carryall. We also carry styles for the beach, as well as smaller hiking pouches and cross bodies. Our bags are designed for comfort, are long lasting, and are manufactured at an industrial women’s cooperative in Puerto Rico. Our handbags are designer quality products and are specially designed to be utilitarian, durable, comfortable and fashionable. We have sold around 16,000 units of the fabric handbag tote. Through the years we have also had around 20 collaborations with different artists for our handbag line.
