Flag 2023 is a project where RC4, as one of NUSSU’s Rag-And-Flag (RnF) 2023 participating bodies, helps to raise funds and conduct engagement sessions with our partner beneficiary, Singapore Association of the Visually Handicapped (SAVH). Hence, fundraising activities such as flower and merchandise sales were conducted progressively to consistently raise funds for our partner beneficiary.
