Tombow Pencil Co., Ltd. (株式会社トンボ鉛筆, Kabushiki-gaisha Tonbo Enpitsu) is a private Japanese manufacturing company of stationery products.

[1] The dragonfly figure ("Tonbo" in Japanese – トンボ) was registered by the company as trademark for its pencils in 1927.

In 1954, the company relocated the headquarters from Taitō to Nihonbashi in Chūō, Tokyo, with expansion of business.

Four years later, the first ballpoint pens and markers were released, which consolidated Tombow as a manufacturer of all types of writing implements.

The company established its first European location in 1980, in Cologne, Germany, the "Tombow Pen & Pencil GmbH".

International operations expanded to the United States (1983 in Westlake Village, California), Thailand (1990 in Bangkok), Vietnam (2003), and China (2011).
