Cello Butterflow

BIC Cello is India’s largest stationery manufacturer and a brand synonymous with knowledge, learning, and everyday innovation. Cello Butterflow, one of its most iconic ranges, is celebrated for its advanced Lubriflow ink system, 0.7 mm fine tip, and ergonomic Elasto grip, which together deliver a consistently smooth writing experience.

As a design agency, our objective was to build a stronger, more distinctive identity system for the Butterflow portfolio while ensuring clarity across its expanding variants. We began by crafting a unique visual mnemonic using the letter ‘B’ from Butterflow. This bold, fluid ‘B’ became the core design device across the packaging-symbolizing the seamless flow of ink while creating an ownable and recognizable brand asset. The form was integrated into the layout architecture to add dynamism and strong shelf presence.

We structured the packaging system to cohesively accommodate variants such as Cello Butterflow Simply Ball, Cello Butterflow Classic Roller, Cello Butterflow Classic Gel, and Cello Butterflow Classic Ball. Each variant retained the master design language while using differentiated colour cues and hierarchy to clearly define its category. For the Butterflow Simply range, we highlighted the core portfolio with a confident range shot anchored by the bold ‘B’, reinforcing smoothness and reliability.

To enhance communication, we developed bold, minimal, and persuasive iconography that translated product benefits-Lubriflow ink system, 0.7 mm precision tip, and Elasto grip-into clear visual cues. Individual pen sleeve designs featured bright colours to distinguish ink types and classifications, enabling easy consumer navigation. The result is a cohesive and modern packaging ecosystem that reinforces Butterflow’s promise of performance, comfort, and everyday excellence.
