Being water-soluble, it seems you can draw on glass windows, and wipe it off with a damp cloth. I bought this in Germany. It's Pelikan crayons. The red color is slightly used. The other colors are mostly unused. Reference book price: 1796 yen The fish-shaped sharpener is not included. I'm happy to combine shipping. I may be able to discount the cheaper shipping cost. - Brand: Pelikan - Quantity: 8 pieces #Germany #Stationery #Crayons #Pelikan
