With this perfect complement to Igloo coolers you will never want to buy ice again! These ice sheets are durable washable and flexible even when frozen. And because they are made with pure water (unlike other ice substitutes which contain chemicals and gels) Natural Ice is faster to freeze and stays cooler longer. Say good-bye to cold ice water melt down mess and say hello to Natural Ice Small (1 lb.) size made for smaller softside and personal size coolers.
