We already use plenty of dry ice for your order. However, if you'd like extra peace of mind, you can purchase a bit more. We wrap each 1 kilogram block of dry ice in kraft paper as the temperature is minus 78 Celsius and should never be touched directly. As a general rule, the larger your order is, the more slowly it will take to defrost because of the density of frozen items. Therefore if you have only a few frozen items, they are likely to defrost faster and may be a good candidate for extra dry ice.
