Long-lasting 2.4mm eyeliner, black brown - Model Name: 1DAY TATTOO REAL LASTING EYE PENCIL - Color: Black - Core thickness: 2.4mm Thank you for viewing. Purchased in July of this year. I often used other eyeliners, so I didn't have many opportunities to use this one, and I've only used it about 2 or 3 times. Photo 4 → Fully extended. There's still plenty left! I will disinfect it with alcohol before shipping. Thank you.
