Dear [Factory Name],
We hope this message finds you well. We want to bring to your attention that we have received numerous complaints from our partners regarding the quality of packaging for our products. Specifically, issues related to the blister size not aligning with the backing card and the presence of sticking out flanges have rendered some items unsellable upon arrival at the stores. As these concerns directly impact our sales and reputation, we kindly request that you give as much attention to the quality of packaging as you do to the toy itself. We appreciate your cooperation and commitment to improving this aspect of our products.
Best regards,
[Your Name]
