Summer hot months are here. Our wax is much harder than some so it does stand up to higher heats however we do not guarantee that they will not get mushy or grimy during shipping. If you would like to add an ice pack or two to your order to help ensure your wax arriving in one piece please feel free to add this to your order. Ice packs are packaged in a zip-lock baggy (bag is not safe to store wax in!) in case of leakage and wrapped in a paper towel just in case of condensation.
