We're looking for your best pricing on Little Boys clothes (Toddler size) with a packing size of 4 pieces per hanger pack. The estimated order quantity is around 42,000 pieces, with potential for more as this could be a year-round program. Please provide details on MOQ per style/color, lead times for samples and bulk production, available colors and customization options, any packaging costs, and your payment terms. We need to finalize this quickly, so your prompt response would be greatly appreciated!
