The guys at Prodir pens of Switzerland were nice to have my doodle (Featuring Tanupon!) up on their official blog, Open. (Thank you!) Prodir makes great pens that are customisable and fun! Something really different from the pens you get in conferences and trade shows, these pens from Prodir write comfortably too. 

イラストはスイスのボールペンメーカー「Prodir」の公式ブログに掲載されました！ 嬉しい〜！ブログ記事はこちらです。（英語のみ）
