They went out of the way to fulfill my request to tape the caps on in case of spillage during shipping - I'm glad they did because one of the caps came partially off in transit but I lost almost no product. This greatly helped some of my plants that have not had nutrients in a while and is a generally good supplement or fix for plants that appear to have a micronutrient deficiency. Mild, organic product that won't burn your plants - great for the beginning gardener.
