text: Shelf life of the product, date manufactured, and when the product was made was missing.
  
  We got an old product or expired product which it did not work for us. We have filed a complain with the Amazon and the seller so far we have not resolve this problem. We mixed the product as recommended on the container. The product was very hard to use it was very sticky. Then it became like a real glue after half hour as shown in the figure above.. The seller told us that you must leave the lid open after you mix it which was not on the instruction. This does not make a sense. We believe that we have received an old product which was sitting in the shelf for more than a year. The shelf life of the product is one year. The shelf life of the oriduct was missing on the container. There was no date on the container when it was made, and when it expire. This is very important. We have filed a dispute against the seller.
