In theory this is 100% biodegradable laundry detergent and is just sheets of it. I like the idea and it seems I save money with it let alone invest in a Catalan company which I love doing because Catalans are always right (they are) and are the brains of Spain. Same as I use Hevy (Catalan too) for working out because it is THE BEST. We'll see if it's any good on the weekend when the electricity is cheaper and I can put a washing. #Natulim #BuyFromEU #SpanishProducts
