CRETACOLOR is an Australian art supply brand, and this is a metallic color drawing set. It's a mega-color type with thick colored pencils with a 6.4mm core diameter, and they have a metallic shine, so they can be used not only for regular paintings but also for decorative purposes. Examples of drawings are also uploaded on YouTube, etc. I have used NO. 8 a little. It's sold at a high price on major online shopping sites, so I think it's a good deal...
