Cute wine corks--dice

I have either 6 or 8 of these dice wine corks. They would be a great gift for Bunco groups or just a fun novelty to put in a decorative wine bottle. I would doubt the quality of this for use with actual wine. I plan to use the one I'm keeping to put in a wine bottle I am painting with chalkboard paint. See pic below the cork; the cork would be soo very cute in these bottles.
