I'm looking to procure thermal till rolls in white color, with specific dimensions that fit my needs. I'm interested in placing an order for 500 units, and I need them delivered to Lusaka, Zambia. Please provide a CIF quote that includes shipping costs to this location, as well as your lead time for production and delivery. Additionally, if you have any options for bulk discounts or different roll specifications that could meet my requirements, please include those details in your response. I am keen to establish a reliable sourcing relationship, so prompt feedback would be appreciated. Looking forward to your reply!
