      Sold as new but the box was previously opened and taped shut. Original box was in terrible shape. I guess all my parts are in it ? Shipping was fast. Skeptical if I would buy from again. For the amount of money I spent for this kit I was expecting better. If there was a rating between Positive and Neutral That's what I would have gave you.

      Greetings Randi! The only reason the Athena Kit would be open is because we quality control every item before shipping. We have had many sealed cylinder kit boxes delivered to customers then come to find out there was damage or incorrect parts when the manufacture packaged it. We feel it's worth it to check the contents of the kits before shipping. Thank you for your patience and understanding. Have a great day! 😀
