Pets AC 18 Acrylic Tumblers Review

We have had 3 cups of this type so far, the cup comes with a special hard plastic straw as shown in the picture. This straw cannot be purchased separately. it should have been included in the package as clearly shown in the promotional image on Amazon. The package did not contain any information that would allow me to contact the seller and I did not see a way to contact the seller on Amazon to resolve this issue.
