This is the Withshan Ruby Pusher product.
This product allows you to manage loose skin easily and safely.
I'm using it with the eraser product from Withshan, and it's great.
It's great for beginners because you can manage your nails safely without bleeding.
They say it condenses ultra-fine special ceramic particles.
