JoyeeBox is designed for children ages 3 and up. The pull-back mechanism is simple enough for preschoolers while remaining engaging for elementary-aged children who enjoy collecting and playing with vehicles.

Yes, JoyeeBox includes 24 completely unique vehicle designs with zero repetition. Each day brings a genuinely new car to discover, maintaining excitement and surprise throughout the entire countdown to Christmas.

JoyeeBox combines durable alloy metal with high-quality ABS plastic. These materials are free from high-concern chemicals, ensuring safe play while providing the weight and durability that make pull-back cars function properly.

Absolutely! Many families establish routines where siblings take turns opening doors or share the growing car collection. JoyeeBox works wonderfully for classrooms too, where teachers reveal one car daily for group enjoyment.

Each vehicle measures approximately 2-3 inches in length, perfectly sized for small hands. They're compact enough for easy storage yet substantial enough for satisfying play, with smooth edges designed for safety.

JoyeeBox cars perform best on hard, smooth surfaces like hardwood, tile, or laminate flooring. While they may move slightly on low-pile carpet, hard surfaces allow the pull-back mechanism to work optimally.

The calendar box and cars are built to last. While the numbered doors are designed for one season, the high-quality vehicles become part of your child's permanent toy collection, providing years of play value.
