O3 Marketing Warehouse centralises the materials your brand uses every day: POS displays, welcome kits, uniforms, event flightcases, promotional products, samples, brochures and campaign packs. O3 Group is a marketing and events partner based in Heverlee (Leuven) that stores and distributes marketing materials across Belgium and beyond when needed. Marketing Warehouse includes the MyBrand portal for stock visibility, online ordering and reporting, so your teams can request materials without chasing separate suppliers. We deliver to stores, jobfairs, hotel meeting rooms and event sites. Our warehouse team handles kitting for launches and roadshows, pick & pack for campaign requests, quality checks on returns, refurbishment of POS material and end-of-campaign stock decisions. Because production and storage work together, new material enters stock with the right reference and photo, while returning equipment is checked by teams familiar with it. You work with one trilingual FR/NL/EN team and one point of contact. Marketing Warehouse is one of our 8 services under 360° Brand Services. Active since 2010, O3 Group brings 15+ years of experience and handles 350+ projects per year.
