The clip is labelled as an old commercial for ST Corporation, listed in Japanese as エステー化学, a company known in Japan for household goods and air care products. The (旧) in the original title simply marks it as the older version, distinguishing it from newer commercial edits shared on soundboards.

关于此声音
Short jingle from an old ST Corporation television commercial in Japan. Creators use this brief nostalgic clip for retro ad parodies and edits.
This is a very brief snippet from an older television commercial for ST Corporation, the Japanese household products company. At under one second, it captures just a fleeting musical or vocal tag typical of Japanese CM jingles, the kind designed to stick instantly in a viewer's memory. The sound is short, bright and abrupt, ending almost as soon as it begins. That brevity is part of its charm, making it feel like a found fragment of broadcast history that can be dropped into an edit for instant retro recognition and a light, nostalgic comic effect.
