The client launched a seasonal 24-day advent campaign and required a rigid calendar box capable of holding mixed-size cosmetic products. The main challenge was maintaining structural stability while ensuring smooth drawer operation and precise compartment alignment.
We engineered a reinforced internal grid structure using high-density greyboard to prevent deformation during shipping. Each drawer size was customized according to product dimensions, and assembly tolerance was strictly controlled to ensure smooth daily opening.
The final solution achieved stable mass production, reduced alignment issues, and delivered a premium unboxing experience for the holiday campaign.
