I purchased this by chance and used it for the first time recently. It worked effortlessly on every pencil I sharpened including brow, lip, and eye pencils. It's the best sharpener I've ever used, and I've had various types over the years. With its ease of use and sharp blade, I doubt I'll need another sharpener for years to come. I highly recommend this product. Believe me, it works!
Pros: easy to use, effortless, catches/stores shavings, sharp blade, sharpens any size pencil
