Maze, Logic & Deduction Puzzles: 1 product from 1 verified supplier in Chenghai. Maze and logic puzzles are made from ABS, PP, or wood, with printed cards, wire paths, and moving pieces assembled by hand in Chenghai workshops. Certification scope here should cover EN71 and the phthalate tests, and buyers need to confirm the report matches the printed card stock and any ink used, not only the plastic body. Ask first about the age grading stated on the packaging, because small balls and magnets change the required testing. Then clarify minimum order quantity per puzzle design, and confirm packing, whether cards are bagged separately, and how instruction sheets are inserted.
