The Slanchogled Sofia, Varna and Online art stores offer organic willow charcoal sticks, pressed charcoal (chalk) – when the charcoal powder is mixed with a binder to form chalk or a block, charcoal pencils with a wooden case and a core of charcoal dust with binder suitable for detailed work.
Slanchogled also offers pastel pencils which are much like charcoal and chalk – in that they have a similar consistency, method of application and final effect.
