I designed the posters and leaflets for Antonio, a Hong Kong-based earphone brand. The design concept focused on creating a cool and tech-oriented theme. Grey was used as the primary color to evoke a sleek and modern aesthetic. The posters and leaflets were specifically created to promote the brand's new series of earphones. Through this project, I successfully captured the attention of the target audience and conveyed the innovative and high-tech features of Antonio's products. The design elements employed in the posters and leaflets effectively enhanced the brand image and generated interest in the new earphone series.
