I bought this last year to use at school, but I ended up using different charcoal, so I'm selling it. It's almost unused, but I opened the charcoal in the second photo (5mm diameter) and used about 5mm of one stick. High-quality charcoal sticks for drawing, allowing for smooth rendering. It cost around 830 yen. - Material: High-quality charcoal - Application: For drawing - Package contents: 12 charcoal sticks (4 sticks x 3 bags) Please see the photos for more details. *The box will be folded for shipping. Please understand. Shipping included. I will ship as soon as possible.
