We take pride in our products. During transportation or storage, it is possible the product is not in correct storage environment. Any type of moisture, even one drop of water, may cause the pacs to stick together or dissolve the film on the pac. It is not expected to occur and we hate to hear that it happened to you. Can you please e-mail us at ecommerce_CIC@henkel.com so a member of our team can speak with you and personally provide assistance?
