I'm interested in sourcing custom luxury packaging solutions for wedding cakes. Specifically, I'm looking for square boxes designed for 6-inch and 8-inch tall cakes. It's essential that these boxes feature a clear window to showcase the cake beautifully and sturdy handles for easy carrying. Could you provide details regarding the materials used, available colors, and any customization options you offer? Also, please include information about the minimum order quantities, lead times, and pricing. Your prompt response will be appreciated as I am eager to finalize this part of my project soon!
