Koh-I-Noor Kneadable Putty Rubber - Original
Kneadable putty rubber by long established Czech brand Koh-I-Noor. These can be moulded into any shape and size, making them ideal for very precise erasing of pencil guidelines from calligraphy. The usual method for using a putty rubber is to press down, lightly twist and lift. The pencil particles sticks to the putty and are removed without rubbing, therefore avoiding any smudges on your paper.
This blue rubber is the 'Original' version which is a medium-soft, slightly firmer putty. Also available as a red 'Super Extra Soft' rubber, which is stickier and more flexible.
Comes in a handy little box. Suitable for pencil, chalk or charcoal.
