Our Philosophy

At GRAMS28, we believe aesthetics, usability and quality are equally important. Through rigorous research and a commitment to our customers’ feedback, we continuously refine our craft to ensure every evolution is intentional and meaningful. 


Form and structure are the two main pillars of our design. Beyond durability, every curve and compartment is intentionally sculpted to balance between striking aesthetics and effortless utility. This ensures that while our bags are built to last, they are also designed to elevate your daily experience.

Form and structure are the two main pillars of our design. 

Through experimentation with lamination methods, we engineered a structural foundation that resists the rigors of daily use, allowing each bag to maintain its ideal shape through time. Beyond durability, every curve and compartment is intentionally sculpted to balance between striking aesthetics and effortless utility. This ensures that while our bags are built to last, they are also designed to elevate your daily experience.

Historic Projects

Beyond our core collection, we curated limited-edition capsules with icons such as De Bethune,

Johnny Roams, Mr Lee, and MV Agusta, to craft refined essentials for every occasion.


These projects were also translated into distinct creative visions with commercial successes where the collections were launched at CES - Las Vegas, ComplexCon Hong Kong, Utah and Tokyo.
