Dear [Recipient's Name],
We have recently received multiple complaints from our partners regarding the packaging quality of our toys, which has resulted in some products being deemed unsellable by the time they reach customers. Specific issues such as mismatched blister sizes and protruding flanges have been highlighted. We urge the factory to prioritize improvements in packaging quality, giving it the same level of attention as the toy itself, to ensure both product safety and partner satisfaction moving forward.
Best regards,
[Your Name]
