This is Dr. Pen’s newest model MS8. It is a balanced weight in your hand, sturdy and well-made. The shape is comfortable making it very easy to use during treatments. You can snap open the first layer of the box and underneath you will find the supplies needed for the treatment. There are two of each size needle for starters then you will need to purchase additional ones. It is conveniently packaged in a plastic case so that it is easy use, store or travel with. The directions for use are clear and there is a Dr. Pen site that can and does give you more information. There is also a FB group that can help educate as well. I’m still searching for just the right serum to use. The machine is so much better than the manual roller type treatment. I’m looking forward to great results. I’m very pleased with this order!
