In your kit, you will receive enough putty for two impression attempts. Once you have taken your first impression, send a picture of your impression to us at info@maxxgard.com or by text to (514) 945-1895. Please wait for our confirmation before you send in your impression.  If we see an issue, we will coach you for your second attempt.  If there is an issue with your second impression, you can order additional putty to try again. This purchase will provide enough putty for two more impression attempts.
