Material and Durability Risks Overlooking the impact of material choice can lead to durability issues; for example, wood and MDF offer sturdiness for adult and kids' puzzles, whereas paper or cardboard may wear quickly in puzzles designed for younger children.
Certification Requirements Insist on suppliers providing ISO 9001, ASTM, EN 71, or CE certifications to ensure safety and quality standards are met, especially critical when sourcing puzzles for children under 8 years.
Puzzle Complexity and Age Appropriateness In practice, most suppliers align the number of puzzle pieces with age groups—25-piece sets suit toddlers under 3, while 500-999 pieces target adults and older kids, so specify this clearly to match your target market.
Packaging Trade-offs and Cost Impact The choice between packaging types like color boxes or blister packing directly affects both cost and consumer appeal; while color boxes enhance presentation, simpler paper cartons can reduce expenses significantly.
