The 7 gram pens are not safe and they will burn you
Ordered a seven gram pen, was sent the incorrect pen and they would not give me a refund. Took a pull and the pen shoots out hot wax. The top of my mouth is blistered and it does this anytime you activate the pen. It just shoots up wax. My pen came with a very large air bubble and they claimed this was normal. I won’t be buying again, customer service is as horrible as their product
