Platinum Pen is launching PRO-USE 241, a further enhanced model of PRO-USE 171 released in 2017. The PRO-USE series designated for professional drafting purposes debuted 35 years ago. The first two digits of the three-digit number in the product name indicate the year of release, and the last digit is counted up each time a derivative model is released. Created based on the 171 model, the newly released model allows you enjoy four writing styles in one mechanical pencil. It also comes equipped with the company’s proprietary “OLEeNU Guard Mechanism” that prevents lead breakage. Different features are equipped in one mechanical pencil so that you can select from four styles to create your own unique feel to the pencil.
