I found one of these tiny razors at Big Lots and later discovered multi-packs at Walmart. They are only 1/8-inch wide! Perfect for cleaning up the area below my brows that is covered in downy hair that is too fine to tweeze. Maybe I'm silly (no doubt), but that hair bothers me when I put on eyeshadow.
Isn't it cute? They even have a comfort grip! The package says they are for eyebrows, upper lip, or
bikini art -- whatever that is.
