Spartan Oil in a refill pouch. One pouch will fill up a 500ml bottle. Keep your premium bottle and refill it with our eco-friendly pouch! The refill pouch is designed to be a short-term package for storing olive oil. We minimize the amount of time the oil is in the refill container and it should be promptly transferred to our premium stoneware bottle upon delivery. However, the refill container can be stored in a cool location for an extended period of time (up to 6 months) if necessary.
