Your lobsters are packed in expanded polystyrene foam coolers (which don’t contain any ozone-depleting CFC’s), with a corrugated printed box around it. We use gel ice unit(s) and seaweed to maintain temperature and moisture. Please note that during certain periods in the spring, seaweed is spawning and may not be suitable for use. Also, during winter storms, it may become too hazardous to harvest the seaweed.
