The unique design of these pencil extenders means they have a lower impact on the environment. To reduce the amount of plastic resin needed to make each extender, Kutsuwa uses seashell particles (a naturally-occurring and environmentally friendly material, seashells are made primarily from calcium carbonate) to reinforce the structure and offer textural contrast.
Each package contains three extenders, one each in beige, green, and sky blue. Fits most pencils.
