I'm reaching out to inquire about a specific product in black that I'm interested in for developing a sample for sports leggings. Could you please provide me with detailed information about the available sizes for this item? Additionally, I would like to know the pricing options. It would be great if you could share any bulk purchase discounts or lead times for delivery as well. Looking forward to your prompt response!
