Meaning
The kanji 合 on a square button, meaning to fit or come together in Japanese. As a button it stands for a passing grade, as in passing an exam or meeting a standard.
Students use it to celebrate exam results, driving tests and certificates: “Language test results are out, 🈴!” It also fits anything that meets the requirements, like a product passing inspection. Pair it with 🎉 or 💯 for a full celebration.
