Designed to maximize the artistic potential of the GlideLiner™ Long Lasting Eye Pencil, this eyeliner pencil sharpener uses the Eisen second blade system to create the ideal tip for broader and smoother lining, softer smudging, and fuller coverage. As innovative as the GlideLiner™ itself, the GlideLiner™ Sharpener features a modern, square design and an internal shavings receptacle. For best results, sharpen GlideLiner™ Eye Pencils prior to each use.
