I'm looking for a small music box designed specifically for happy birthday occasions. Ideally, it should have a charming design that appeals to both children and adults. I'm interested in various styles and themes that could complement birthday celebrations. Additionally, please provide details on the sound quality and any customization options available, such as engravings or personalized messages. Could you also let me know about your minimum order quantities, pricing, and lead times for production? I'm aiming to find a reliable supplier for potential bulk purchases, so any information on your manufacturing capabilities and previous work in similar products would be helpful. Looking forward to your response!
