Thank you for your question. These are 1/3oz which would be closest to 10ml in size. We do offer bottling and packaging services. Shipping costs vary depending on the weight of the package, service chosen and destination. Shipments to Nigeria are recommended to use a freight forwarder that we would ship to as USPS, UPS and DHL will not provide insurance on a package shipping to Nigeria. We also cannot accept Credit Cards from NIgeria.
