Prockey PROCKEY PM-150TR (8 colors): Black, Blue, Light Blue, Green, Yellow, Soft Pink, Red, Brown *Plus one red pen as a bonus. I purchased this set but rarely used it, so I'm selling it. While I don't see any noticeable stains, I would appreciate it if you could understand that this is a used item before purchasing. Product Features: * Twin type with fine round tip and broad square tip, refillable. * Mitsubishi Pencil's Prockey uses water-based pigment ink. This means that when drawing lines on drawing paper, the ink is less likely to bleed through to the back, and you can work without worry even when writing on tables or flooring. * Packaging will be done with recycled materials and simple packaging. Thank you very much! Mitsubishi Pencil Water-based Pen Prockey Twin 8 Colors PM150TR8CN Brand: Mitsubishi Pencil
