西班牙采购需求：手摇纸质音乐盒，纸质音乐盒，纸条手动音乐机芯，音乐盒

I'm interested in a variety of boxes and would like to gather some details. Could you please provide information on the minimum order quantities for these boxes? Are they customizable in terms of design or size? Additionally, I'm curious about the pricing structures you offer for different quantities. I would also like to inquire about the musical movement you have, specifically the 18-note pull-string version, as well as any handcrafted options available. What types of music can customers choose from, and how long does each piece play? Lastly, is the pull-string musical movement reusable, or is it designed for one-time use only? Looking forward to your response!
