I'm looking to order Size 5 products and would like to know what options you currently have available. It's important for me to understand the variations in terms of material, color, and any additional features that might be offered for this size. Could you also provide information on pricing, bulk order discounts, and estimated lead times for delivery? I want to ensure we can meet our upcoming project deadlines. Any details on these would be greatly appreciated!
