The Flemish Agency for Roads and Traffic (Agentschap Wegen & Verkeer) approached PrintPlace with a request to design and produce customized keychains. Armed with a rough concept, we elevated their vision by not only designing the keychains but ensuring they were production-ready. Upon design confirmation, prototypes were swiftly printed for physical assessment. Following prototype approval, the keychain underwent customization using our mass customization tool, generating hundreds of unique designs within hours. These custom keychains were then batch-printed at an affordable price point and delivered punctually. This case exemplifies how mass customization can be both accessible and cost-effective without compromising on quality or lead time.
