Tombow Pencil Co., Ltd. (Head office: Kita-ku, Tokyo; President: Junichi Fukushima) announced the addition of five new colors to plastic MONO Eraser series. The new colors will be added to the series as standard items from October 2, 2025; rolled out sequentially at stationery stores, stationery corners and other locations nationwide.
Suggested retail prices for the single pack eraser is 154JPY (140JPY excluding tax) and 462JPY (420JPY excluding tax) for the 3-pack (purple, green, and pink set).

This product is an addition to the flagship blue-and-white “MONO Eraser (PE Series)” series with erasing power comparable to that of the standard “MONO Eraser” (based on erasing performance/JIS measurements).
Based on the popular “Medium Size” (size: 23 x 11 x 55 mm/product number: PE-04A equivalent). Available in five refreshing colors (from left in the photo): blue, green, gray, pink, and purple. This marks the first time we have made multicolored base material MONO Erasers (excluding the achromatic black).

With MONO Colors we hope to boost motivation and make erasing fun by reducing stress caused by erasing mistakes. Also, by adding color to notebooks we want to brighten up the learning environment.
