The cup in the listing is the ten ounce size. I also have a five ounce cup if you prefer a smaller size in the same shop section.
NOTE: The insert is NOT cardstock or regular paper. It is a special material that is washable, water-resistant, tear-resistant, biodegradable and outranks ordinary paper, cloth, and cardstock. It is strong stuff and will handle almost anything that would destroy ordinary paper.
Be sure to include the letter or letters you would like for the monogram. You can do this in the "Message to Seller" box during the check out process.
Don't forget to view the coordinating pieces.
