I prefer a roller vs this stamp. Also please note that if you are looking for your skin care to be delivered deeper in your skin this is the needle size you need. If you are looking to stimulate collagen production you will need .5mm or bigger. Sent back due to the description saying that it would produce collagen, but upon further research I found out that is not the case. So bought a different roller that is .5mm.
