A5 size reference notebook and ballpoint pen set. The notebook features 80 lined sheets (80 g/m?) made from recycled milk cartons (up to 70%), a coloured paper spinal, and a pen loop. In the pen loop, there is a click-action ballpoint pen in matching colour of the notebook. The pen has a barrel made of the same recycled milk carton material and the button, clip, and tip is made of coloured PLA plastic. The pen features a black refill inside. Used milk cartons are collected, sorted, processed, and turned into paper, truly turning waste into something useful.
