Tombow Ippo Blue Colored Pencils 12 Pieces

Tombow Ippo is a series of colored pencils designed as stationery for school kids. Although its original use is answer correction, you can use these pencils as a drawing tool.

In some schools in Japan, Prussian blue (a darkish blue that is close to indigo) pencils are used for the second correction of the exams or worksheets that were previously marked with a red pencil to make the learners easier to distinguish between the first and second corrections. As a result, it promotes their use to establish the practice of reviewing.
