We warranty all products we sell. From the 710Pen disposable to the Yocan Thor. We are a factory authorized seller of our products we stock. You can order knowing we will make it right. We will always try and carry the best products for our value minded customers. Sometimes products will arrive inoperable. We wish everything was 100% perfect but we know sometimes units will arrive that don’t perform out of the box. You certainly wouldn’t want people handling your units before shipping. We ship new clean factory packeaged vapes and accessories. If you have a warranty request, please email sales@710Pen.net when you reorder and we will make it right. Service is where we will stand apart from the competition.
