How about using neon LEDs to open your nail salon? I think that most nail salons are opened as individual businesses rather than as large-scale businesses. In the beginning, you want to prepare a sign that will help you attract customers as much as possible, but you want to keep costs down. In such cases, neon LED signs are recommended because 1) they are eye-catching and attract customers, and 2) they cost an average of 20,000 to 40,000 yen, making them very cost-effective!
