The key components of the Progresso Aquarell coloured pencils are rich, top quality and perfectly dispersed pigments carefully selected and purchased from renowned producers around the world. Their light permanency and dosed concentration also influences the final result and durability of the artwork. Therefore a high concentration of dosing of pigments has been prescribed for this product in its entire colour range. Another important component is white clay, usually bleached kaolin of the highest purity and fineness. It gives our coloured pencils, together with the addition of binders and other additives, an unsurpassable ability to make a unique stroke on the paper or other medium. Another important agent of the formula ensures the excellent solubility of all the components. The aquarelle technique can be achieved even with a few drops of water distributed by a fine brush. The options, or rather techniques of application are many. You can dilute the strokes on paper, coloured dust (prepared with sandpaper) or chips (prepared with a knife or sharpener). Thanks to the unique diameter of the lead, 7.1 mm, and thanks to the sufficient mechanical firmness it is not necessary to fix it in wood. This considerably eliminates losses during sharpening and maximizes use of the entire lead. This characteristic ability brings this product a high utility value and excellent artistic potential for every user. No component used in production contains toxic or otherwise harmful substances and the final product is therefore suitable for all age categories.
