Tombow Pencil Co., Ltd. (President, Akihiro Ogawa, head office, Kita-ku, Tokyo) is a school stationery series Ippo that makes use of the Guardian's mind to enroll children! I will release a pen for the name writing that the pen tip does not become thick even if I repeat a name etc. from (a little). The launch will start from the end of January at the 2013 New entrance fair and corner of nationwide dealers. The release date will be voluntary for each dealer.

The product name is “Ippo!” The manufacturer's suggested retail price is 157 yen (body Price 150 yen) in the name pen. Stripes and stars are two patterns. The annual sales plan is 300,000 and 45 million yen (retail price). This product is an oil marking pen with two pen nib of fine print and ultrafine, and the ink color is black.
The advantage of this product is that even if you write repeatedly, the nib is less likely to thicken and the initial line width lasts longer. The shape retention force for pen tip pressure is twice as strong (our experiment) as compared with our conventional products, and it is suitable for writing letters such as names and symbols repeatedly. The reason for the pen tip is not to be thick is that the pen tip was polished round to the dome type. The conventional nib was tapered to become thinner ahead. Nib = Photo right = Acrylic core, “fine” is a polyacetal core. (Dome-shaped processing is fine print only)
