Taiwanese is the local language of Taiwan while the paper is the medium to carry the emotion and to remember the old days. So, we named it Mui Kai paper and expecting this special made paper can deliver our thoughts and pass it on. “A world class dancer needs a partner of equal measure to perform at the highest level, and a fountain pen deserves no less in the notebook it is paired with.” In the very beginning, Mui Kai paper was originally manufactured for exporting to Germany only. Nevertheless, we tried to adjust the details and made it allows the fountain pen nib to glide effortlessly over it. The quality is there for everyone to see which can even compete with Japan or Germany made papers. It is cream paper with great smoothness and wonderful show-through resistance. The unique, unlimited graph rule and the soft cream color is always pleasant to look at. When you find this paper for your fountain pen, you will know that the heavens will open up and choirs of angels will sing. The graph notebook is also known as squared notebook. To meet the public demand, we arranged different designs on both sides of paper. Its lined on the left pages and graph ruled on the right ones. The lines are easy to write down the to-do list and classify all the schedules while the graph ruled are the best choices for engineers, artists and notebook addicts. To make it easier to use, the notebook can even be unfolded completely. <Shipping Details> －Please note that we ship from Monday to Friday, not including holidays. <Returns Policy> －Buyers may return an order and request for a refund (partially or in full) within 7 days counting from the day after the order arrives at the recipient’s address. －Buyers are responsible for all shipping fees including the shipping fees of returns.
