L'ARRONDI solidaire is an initiative by the association MicroDon, allowing everyone to make small donations by rounding up their receipts or salaries for the benefit of over 200 charities. These small, collective actions create a significant social impact, providing long-term support to multiple organizations. Adopted by over 600 companies and nearly 8,000 stores, MicroDon has raised more than 28 million euros. For the first time, many brands have teamed up with L'ARRONDI to launch a humorous and educational campaign, using their names to capture consumers' attention and inspire generosity.
