For the San Fermín 2026 Chupinazo, at Hinchables Pro we produced 150 cm diameter inflatable advertising spheres, fully customised for a promotional activation in the centre of Pamplona.
The objective was to create a large-format visual element capable of standing out among thousands of people and providing strong brand visibility during one of Spain’s most crowded and iconic events.
Using the corporate colours and logos supplied by the client, we produced several custom inflatable spheres, adapting each graphic design to the corresponding brand identity.
The challenge: standing out in a crowded event
San Fermín attracts thousands of people to the streets of Pamplona every year, so any promotional activation needs to capture attention even in a highly saturated visual environment.
The challenge was to create eye-catching, durable and fully customised inflatable advertising spheres, while maintaining clear logo visibility and strong brand recognition from different viewing angles.
The 150 cm diameter provided an important visual presence while remaining suitable for use in a dynamic promotional activation.
Design and customisation of the spheres
For this project, we manufactured 150 cm diameter inflatable spheres in different corporate colours, applying the logos and graphic messages supplied by the client.
During development, we focused particularly on:
- adapting the artwork to the spherical surface;
- maintaining the correct proportions of the logos;
- reproducing the corporate colours;
- ensuring good overall visibility;
- creating a consistent visual result across the full set.
The aim was to achieve a clean, recognisable result with strong visual impact both at close range and from a distance.
Inflation tests in our warehouse
Before delivery, we carried out inflation tests in our warehouse to check the final result of each sphere.
During this stage, we verified the shape, volume, overall finish and correct application of the customised graphics.
These pre-delivery tests allow us to inspect each piece before use and confirm that the shape and personalisation match the intended result.
In this case, the spheres featured different combinations of colour and branding while maintaining a coherent visual identity across the entire promotional activation.
The result during San Fermín 2026
Once used during the San Fermín 2026 Chupinazo, the spheres clearly stood out among the crowd.
Thanks to their size, colour and customisation, they became easily recognisable visual elements in an environment filled with thousands of people.
The spheres also appeared in images published by different media outlets during coverage of the event, further increasing the visibility of the promotional activation.
The project demonstrates how large inflatable advertising spheres can become highly effective branding tools for events with very large audiences.
Custom inflatable spheres for events
Inflatable spheres are a particularly versatile solution for projects where high visibility, originality and full customisation are important.
They can be used for events, festivals, brand activations, sports events, concerts, trade fairs, product launches and promotional campaigns.
At Hinchables Pro, we manufacture custom inflatable advertising spheres in different sizes, colours and finishes, adapted to the visual identity and specific requirements of each project.
Special thanks to Blanca for the trust, collaboration throughout the process and the opportunity to be part of such a special activation during San Fermín 2026.
