There was a glitch with the design on the expiration box on the last page of the design. Seller told me it was a cache stored in phones browser. I trusted him and gave him the benefit of doubt but after delivery I discovered it was an error in the code. When I tried to contact seller, he made himself unavailable to contact and disappeared.
