This microneedling pen is really well made and great quality! It comes in a nice plastic storage case with instructions, single use needles, charging wire and a plug. The depth is adjustable up to 2.5mm for different skin issues and skin areas. I will be using it on my forhead wrinkles and neck lines. Micro needling is proven to heal and improve skin issues with a few sessions so I look forward to seeing the results. I like that is comes in a nice case for storage and protection too. It is a great product which will last a very long time.
