I'm reaching out to inquire about a specific product I'm interested in. I'm looking for options that come in 3 to 5 colors, with each piece measuring approximately 3-5cm by 3-5cm. It would be great to know the variety of colors available and whether you can accommodate custom color requests. Additionally, I would like to understand the minimum order quantity for this product. Are there any specific requirements or limitations I should be aware of when placing an order? Your insights would really help me in making a decision, so I appreciate any details you can provide!
