Very nice product

Its something metal like substance with sharp edges

Both roller n serum r very gud derma roller works well plus the serum which is given along does wonders to your skin seller is very very bad dont purchase this product time west this product is worth it to guys who are actually serious about getting rid of scarsbut u have to use it like 2 times weekand it can be of any brand not particularly this one how to use vitamin c serum

May u tell me good product well packaged i can see the results for roller but i think serum should be more effective there is no any doubt in that it doesnt contain any needles in this roller
