How is the new AMP MD Derma-Roller different from the original version?

The new AMP MD Derma-Roller has been completely re-engineered to feature a sleek, ergonomic handle for improved control and an ultra-smooth glide. The micro-exfoliating tips are still the same length and are constructed of high-quality, laser-cut stainless steel. A dual-purpose cleansing and storage container and convenient snap-on cap make maintenance a breeze.
