Air Spencer

Air Spencer is a brand of Eikosha Co., Ltd., a Japanese manufacturer of automotive fragrances founded in 1948 in Osaka, Japan. The company is one of the longest-running car air freshener manufacturers in the world. The CS-X3 is the flagship product line — a compact gel can with an adjustable sliding lid that controls fragrance intensity. The "Squash" scent variant is by far the best-known product outside Japan, achieving cult status in JDM (Japanese Domestic Market) car culture and among automotive enthusiasts worldwide. The name "Squash" refers to a Japanese fragrance category — a fruity, candy-like citrus blend — not the vegetable. Eikosha does not publish English-language Safety Data Sheets for the Air Spencer product line. SDS documentation may exist in Japanese but is not publicly indexed through standard Western SDS repositories (chemicalsafety.com, MSDS.com, brand website). Products are manufactured in Japan and distributed through third-party importers in the US market.
